33.1 OVERVIEW:
33.11 Each alliance faction controls oil sources (33.2) which produce oil counters (33.4). Oil counters represent the oil resources available for use in the game. Oil production from certain oil sources may be affected if the oil source is damaged or destroyed (33.3).
33.12 Oil counters are used to offset oil effects, allow the use of air and naval units and permit unit construction at normal cost. Oil is also needed for BRP base growth. Oil counters may be:
A. Moved to unlimited supply sources by land or sea to augment the oil reserve associated with that unlimited supply source;
B. Shipped by sea to a supply zone and then used in that supply zone; or
C. Used in the supply zone in which the oil counters are produced.
33.13 Units and hexes supplied from unlimited supply sources suffer any oil effects associated with the unlimited supply source itself, unless oil is produced in or shipped to and consumed in their supply zone. Air and naval units have the supply and oil status of the hex in which they are based (30.61).
33.14 Oil counters which are not used in the turn they are produced may be retained in an oil reserve for use in a future turn (33.422).

33.2 OIL SOURCES:
33.21 MAPBOARD BOXES: The following mapboard boxes produce the specified number of oil counters per turn:
A. U.S. BOXES: Unlimited.
B. URALS BOX: One. The oil production of the Urals box is increased by one for each IC diverted to oil production (37.65).
33.22 OIL CENTERS: The following oil centers produce the specified number of oil counters each turn unless their capacity is reduced by damage:
A. PLOESTI: Three.
B. MOSUL: Three.
C. ABADAN: Three.
D. AHWAZ: Three.
E. BAKU: Two
F. GROZNY: One
G. MAIKOP: One.
H. PALEMBANG: Three.
I. BRUNEI: Three.
33.23 SYNTHETIC OIL PLANTS:
33.231 OIL PRODUCTION CAPACITY: Each undamaged synthetic oil plant produces one oil counter each turn and is also an unlimited supply source (30.222B).
33.232 GERMANY ONLY: Only Germany may build synthetic oil plants, although Russia may divert ICs to oil production (37.65).
33.233 STARTING LEVEL: Germany begins the game with two synthetic oil plants, each of which must be placed in a different German objective.
33.234 PRODUCTION: Germany may produce additional synthetic oil plants at a cost of five RPs per synthetic oil plant (reduced by one for each military breakthrough). Synthetic oil plants are produced at the start of the Axis player turn and may be used as an oil source in the turn in which they are produced. Newly produced synthetic oil plants must be placed in an objective in Germany which does not already contain a synthetic oil plant. Once each German-controlled objective in Germany contains a synthetic oil plant, a second synthetic oil plant may be placed in an objective which already contains an oil plant. No more than six synthetic oil plants may be in play at any one time.
33.24 THE INTERNATIONAL MARKET: The international market produces oil counters to which all neutral powers have access, although Japanese access may be impeded by an oil embargo (33.4521).

In classic A World at War, only Japan requires access to the international oil market.

33.25 MINOR COUNTRY CAPITALS: A minor country capital, which provides full supply to all units of the minor country (30.24), also provides oil to that minor country's units (only). This oil supply is distinct from the oil used by alliance factions and is not represented by oil counters. After association or activation, minor country oil requirements may also be met using their major power's oil counters.

33.3 OIL PRODUCTION:
33.31 DAMAGE AND DESTRUCTION OF OIL SOURCES:
A. MAPBOARD BOXES: The oil production capacity of mapboard boxes may not be damaged or destroyed.
B. SYNTHETIC OIL PLANTS: Synthetic oil plants may be damaged by or destroyed by enemy bombing and are destroyed if they come under enemy control (33.32).
C. OIL CENTERS: Oil centers may be damaged by enemy bombing or when they come under enemy control after ground combat (33.33).
33.32 SYNTHETIC OIL PLANTS:
A. DAMAGE: Synthetic oil plants may be damaged by enemy bombing (26.72A). Production from damaged synthetic oil plants is reduced by one partial oil counter for each damage marker. One damage marker is removed each turn, at no BRP cost (26.72B).
B. DESTRUCTION: A synthetic oil plant is destroyed if it has five or more damage markers (26.72C) or if its hex comes under enemy control.
33.33 OIL CENTERS:
A. DAMAGE FROM BOMBING: Oil centers may be damaged by enemy bombing (26.73A). For each odd-numbered damage marker, the oil production of an oil center is reduced by two partial oil counters; for each even-numbered damage marker, the oil production of an oil center is reduced by another three partial oil counters. Every two damage markers therefore reduce the oil production of an oil center by one oil counter (26.73A).
B. DAMAGE FROM CAPTURE: When an oil center comes under enemy control through ground combat, it incurs one level of damage for every five factors defending the oil center (rounded up), taking into account the defender's DM: (0 to 4 defense: no damage; 5 to 9 defense: one damage marker; 10-14 defense: two damage markers; and so on).
C. DESTRUCTION: Oil centers may not be destroyed.
33.331 REPAIR: Each turn, Germany, Japan, Britain and Russia may each remove two damage markers from oil facilities under their control. These repairs are made, at no BRP cost, at the end of the owning player's turn (26.74).

33.4 OIL COUNTERS AND RESERVES:
33.41 OIL COUNTERS:
A. At the start of each player turn, during the oil adjustment phase, newly-produced oil counters are placed in each oil source under friendly or neutral control from which moving alliance factions may draw oil.
B. Oil counters may be moved by land from an oil source to an oil reserve as permitted by 33.43A.
C. Oil counters may be moved by sea from an oil source to an oil reserve as permitted by 33.43B.
D. Oil counters which remain in an oil center and are not used in the course of the moving player's turn are eliminated at the end of that player's turn.
33.411 USING OIL COUNTERS: Oil counters may be used to offset oil effects (33.6) during the oil adjustment phase, initial supply determination, or post-combat supply determination (air, naval and army oil effects) and during the unit construction phase (construction oil effects - 33.52A, D); or during either player turn to allow the use of additional air and naval units (33.8).
33.412 Oil counters are removed from their oil reserve when used.
33.42 OIL RESERVES: Unused oil counters in an oil reserve remain in that oil reserve and may be used in a future turn. Each oil reserve is associated with one or more unlimited supply sources. Oil counters in an oil reserve are placed on the relevant major power force pool charts, mapboard boxes or city. As the game progresses, oil reserves may increase or decrease, depending on whether production exceeds consumption or vice versa. Oil counters in oil reserves are not subject to damage or destruction except as set out in 33.424.
33.421 OIL RESERVES AND SUPPLY SOURCES: Each oil reserve is associated with the following unlimited supply sources:
A. EUROPEAN AXIS: Berlin, Rome and each German objective containing an undamaged synthetic oil plant.
B. JAPAN: Tokyo, Osaka, Kagoshima and Seoul.
C. RUSSIA: The Urals box.
D. WESTERN ALLIES (Europe): London and Paris.
E. WESTERN ALLIES (India box): Colombo and the India box.
F. WESTERN ALLIES (South Africa box): The South Africa box.
G. WESTERN ALLIES (Pearl Harbor): Pearl Harbor.
H. WESTERN ALLIES (Australia box): The Australia box.
I. WESTERN ALLIES (Manila): Manila.
33.422 MAXIMUM OIL RESERVES: Each oil reserve may contain a maximum number of oil counters. These maximums apply to each oil reserve at the end of each player turn, and any oil counters in excess of the maximum are eliminated. The maximums and starting levels for each oil reserve are:
A. EUROPEAN AXIS:
B. JAPAN:
C. RUSSIA:
D. WESTERN ALLIES (Europe):
E. WESTERN ALLIES (India box):

In classic A World at War, the maximum value of the India box oil reserve is three and it starts with three oil counters in it.

F. WESTERN ALLIES (South Africa box):
G. WESTERN ALLIES (Pearl Harbor):
H. WESTERN ALLIES (Australia box):
I. WESTERN ALLIES (Manila):
33.423 CAPTURE OF OIL RESERVES PROHIBITED: Oil counters may not be captured. The capture or surrender of a location listed in 33.422 reduces the defender's maximum oil reserve level but has no effect on the attacker's current or maximum oil reserve level.
33.424 DESTRUCTION OF OIL RESERVES: Oil counters in an oil reserve may not be bombed or otherwise damaged or destroyed except by the capture of objectives which reduce the maximum capacity of an oil reserve to less than the number of oil counters in that oil reserve. (EXCEPTION: If, during its initial surprise attack, Japan carries out a second air strike against Pearl Harbor, Japan may target the oil counters in the Pearl Harbor oil reserve. The oil reserve is attacked as a single target using the Naval Attack Table. No DRMs are applied to the air attack dice roll. On a “1” air attack result, one oil counter is destroyed. On a “2” air attack result, two oil counters are destroyed. On a “3” or greater air attack result, all three oil counters are destroyed).
33.425 CAPTURE OF PARIS AND LONDON: If the Axis capture both Paris and London, oil counters in the Western Allied (Europe) oil reserve may be used in conjunction with sea supply traced from the Atlantic U.S. box. If the Axis also capture Birmingham and Manchester, the Western Allied (Europe) oil reserve is eliminated altogether.
33.43 INCREASING OIL RESERVES: Oil reserves may be increased by moving oil counters from an oil source to the objective containing the oil reserve or, for Russia, the Urals box. Oil counters from newly-captured oil centers may not be used in the turn of capture. Oil counters may be moved as follows:
A. BY LAND: By tracing a land supply line from an oil source to the destination during initial supply determination or post-combat supply determination in the owning player's turn. Oil counters shipped by sea to a port may then be moved by land to their destination, and vice versa.
B. BY SEA: By tracing a sea supply line from an oil source to the destination port or mapboard box during initial supply determination or post-combat supply determination in the owning player’s turn. One transport (Japan, Western Allies, Western Allied oil shipments to Russia) or three destroyer factors (European Axis) are required to sea escort each oil counter shipped by sea. Subject to enemy air attack or naval interception, oil shipments by sea arrive immediately after they are made. Russia may not ship oil by sea.

The use of European Axis destroyers to trace oil supply by sea will usually arise only in the rare instance where the Axis have captured Mosul or a Russian oil center but do not have a land route to the captured oil center.

33.431 OIL COUNTERS REMOVED AT THE END OF EACH PLAYER TURN: At the end of each player turn, all oil counters which are not in an oil reserve are removed from play. There is no exception for Western Allied oil counters which are intended to be shipped to another destination in a future turn.

The maximum South African oil reserve is three oil counters. There may be no more than three oil counters in the South Africa box at the end of any Western Allied player turn, even if the Western Allies promise to ship any surplus oil counters to the India box in the next turn.

33.44 EUROPEAN AXIS:
33.441 OIL STATUS OF ALL UNLIMITED SUPPLY SOURCES IDENTICAL: The oil status of all European Axis unlimited supply sources is determined by the oil consumed from the European Axis oil reserve.
33.442 EUROPEAN AXIS OIL SOURCES: Each turn the European Axis may augment its oil reserve with oil from the following sources if a supply line may be traced from the indicated oil source to any objective in Germany in which unit construction is permitted:
33.4421 PLOESTI: Three oil counters from Ploesti, including by tracing a supply line from a neutral or Axis-controlled Rumania over neutral minor country hexes. The European Axis may not draw oil from Ploesti if:
A. Russia controls Ploesti and either Russia and Germany are at war or: B. Ploesti is under Western Allied control.
33.4422 SYNTHETIC OIL PLANTS: One oil counter from each undamaged German synthetic oil plant.
33.4423 CAPTURED OIL CENTERS: Oil counters from Mosul, Maikop, Grozny and Baku if they are under Axis control. The Axis may not use oil produced in Abadan or Ahwaz, as no facilities existed for transporting it overland to the Mediterranean.
33.4424 INITIAL EUROPEAN AXIS OIL RESERVE: European Axis oil consumption is not tracked and the European Axis oil reserve is deemed to contain ten oil counters until the start of the first Axis player turn after:
A. NAZI-SOVIET PACT: If the Nazi-Soviet Pact is in effect:
B. NO NAZI-SOVIET PACT: If there is no Nazi-Soviet Pact:

In classic A World at War, the Nazi-Soviet Pact exists and rule 33.4424B does not apply.

33.45 JAPAN:
33.451 OIL STATUS OF UNLIMITED SUPPLY SOURCES: The oil status of Tokyo, Osaka, Kagoshima, Seoul and all Japanese naval and SW units in the Pacific and Indian Ocean SW boxes is determined by the oil consumed from the Japanese oil reserve.
33.452 JAPANESE OIL SOURCES: Each turn Japan may augment its oil reserve with oil from the following sources if it can trace a supply line from the indicated oil source to any objective in Japan or Manchuria in which unit construction is permitted:
33.4521 THE INTERNATIONAL MARKET: Japan may obtain the indicated number of oil counters from the international market:
A. NO EMBARGO: Unlimited, if the U.S. has not imposed an oil embargo on Japan in a previous game turn. An oil embargo has no effect on Japan's oil supplies in the game turn in which it is imposed.
B. PARTIAL EMBARGO: Three oil counters per turn for the two Japanese turns after the U.S. imposes an oil embargo.
C. FULL EMBARGO: None, beginning in the third turn after the U.S. imposes an oil embargo.
D. WAR: None, if Japan and the U.S. are at war, other than in the turn in which Japan goes to war with the U.S.
EXAMPLE: The U.S. imposes an oil embargo on Japan in Summer 1941. Japan receives three oil counters from the international market in Fall 1941, and another three oil counters in Winter 1941. Starting in Spring 1942, Japanese oil supplies depend on Japanese control of the Dutch East Indies oil centers and the number of available Japanese transports.
33.45211 OIL EMBARGO:
A. TIMING: An oil embargo may be imposed at any time during a turn, including before, during or after the Japanese player turn, when USJT reach 20. Once imposed, an oil embargo cannot be lifted.
B. EFFECT OF DUTCH EAST INDIES DIPLOMACY: Japanese and British flags in the Dutch East Indies at the end of Storm Over Asia weaken or strengthen the American oil embargo as follows:

In classic A World at War, rule 33.45211B does not apply.

33.4522 BRUNEI AND PALEMBANG: Three oil counters from each of Brunei and Palembang. Japan may only ship oil from Brunei or Palembang if they are under Japanese control at the start of the Japanese player turn. Oil counters produced in Brunei and Palembang must be shipped to the Japanese oil reserve to be used (EXCEPTION: Starting in Spring 1944, oil from Brunei and Palembang may be used in those hexes to offset naval oil effects. Japanese naval units which use oil in Brunei or Palembang must be based in those ports). Oil counters which are unused by the end of the Japanese player turn are eliminated. Japan may not create an oil reserve in Brunei or Palembang.
33.4523 ASSIGNING TRANSPORTS TO CARRY OIL: Japan may ship oil during initial supply determination and post-combat supply determination by assigning one transport to sea escort each oil counter. The number of Japanese transports which may be assigned to sea escort oil each turn is half (round up) of the number of transports available in the SW box in question: 1 transport: 1 oil counter; 3 transports: 2 oil counters, 5 transports: 3 oil counters; 7 transports: 4 oil counters; 9 transports: 5 oil counters; 11 or more transports: 6 oil counters, the maximum oil production of Brunei and Palembang per turn. Japanese oil shipments are subject to the following restrictions:
A. Japanese transports may sea escort oil from Brunei only if Japan controls Balikpapan at the time the oil is shipped.
B. Japanese transports may sea escort oil from Palembang only if Japan controls Batavia at the time the oil is shipped.
33.46 RUSSIA:
33.461 OIL STATUS OF ALL UNLIMITED SUPPLY SOURCES IDENTICAL: The oil status of all Russian unlimited supply sources is determined by the oil consumed from the Russian oil reserve.
33.462 RUSSIAN OIL SOURCES: Each turn Russia may augment its oil reserve with oil from the following sources if it can trace a land supply line from the indicated oil source to the Urals box off the eastern edge of the European mapboard as far north as A62 and as far south as Z53 or through the Persian hexes on the eastern edge of the European mapboard if they are under Allied control and the Persian BRP route is open:
33.4621 URALS BOX: One oil counter from the Urals box.
33.4622 RUSSIAN-CONTROLLED OIL CENTERS: If under Russian control, oil counters from: Maikop, Grozny and Baku; Abadan or Ahwaz (a maximum of one oil counter per turn from Persia, provided the Persian BRP route was opened on a previous turn); Mosul (if the Allies control Turkey); and Ploesti.
33.4623 WESTERN ALLIED OIL SHIPMENTS TO RUSSIA: Oil counters may be shipped to Russia by the Western Allies, in addition to or instead of BRP grants. Provided the route in question is open, each turn a maximum of two oil counters may be sent via Murmansk and one oil counter via each of Persia, Turkey and Siberia. Each oil counter shipped counts as 10 BRPs against the limit of the BRP route used and the overall Western Allied-Russian BRP grant limit. Each oil counter shipped via Murmansk or Siberia requires a Western Allied transport; oil counters from Abadan or Ahwaz through Persia or from Mosul through Turkey do not. The Western Allied and Russian BRP levels are not affected by oil shipments. Western Allied oil counters shipped to Russia may be used in the Russian player turn in which they are received or may be added to the Russian oil reserve and used in any subsequent Russian player turn. See 40.25.
33.4624 INITIAL RUSSIAN OIL RESERVE: Until the Axis capture Maikop, Grozny or Baku, Russia does not track its oil consumption. If the Axis capture a Russian oil center, Russia tracks its oil consumption and the Russian oil reserve is considered to be at the maximum level permitted by 33.422C. If Russia restores its prewar oil situation by recapturing all its oil centers and starts its player turn in control of Maikop, Grozny and Baku and with six oil counters in its oil reserve, it is no longer required to track its oil consumption.
33.47 WESTERN ALLIES:
33.471 OIL STATUS OF UNLIMITED SUPPLY SOURCES VARIES: The oil status of each Western Allied unlimited supply source is determined as follows:
33.4711 LONDON AND PARIS: By the number of oil counters consumed from the Western Allied (Europe) oil reserve.
33.4712 PEARL HARBOR: By the number of oil counters consumed from the Western Allied Pearl Harbor oil reserve.
33.4713 MANILA: By the number of oil counters consumed from the Western Allied Manila oil reserve.
33.4714 COLOMBO: By the number of oil counters consumed from the Indian oil reserve.
33.4715 UNITS IN WESTERN ALLIED MAPBOARD BOXES: Units in the South Africa, India and Australia boxes are not subject to oil effects, and the South Africa, India and Australia boxes are considered to be fully operational bases for air and naval units, regardless of the number of oil counters consumed from their oil reserves. This status only applies to units in the mapboard box in question, and is lost when units leave their mapboard box:
A. GROUND UNITS: Ground units which leave their mapboard box lose this status unless an oil counter is used to offset the army oil effect.
B. AIR UNITS: Air units may oppose Japanese bombing of the India and Australia boxes without using oil, but air units which leave their mapboard box lose their status unless an oil counter is used to offset the air oil effect.
C. NAVAL UNITS: Naval units may oppose raiders without using oil, but lose this status if they conduct offensive operations or interceptions from their mapboard box, or if they change base or redeploy to a port on the mapboard, unless oil is used to offset the naval oil effects for those naval units.
33.4716 SUPPLY FROM WESTERN ALLIED MAPBOARD BOXES: Supply from Western Allied mapboard boxes depends on the mapboard box:
A. The U.S. boxes have unlimited oil. The oil status of supply zones drawing supply from the U.S. boxes is determined as per 33.533.
B. The oil status of supply zones drawing supply from the South Africa box is determined as per 33.533.
C. The oil status of any supply zone drawing supply from the India box is determined by the number of oil counters consumed from the Indian oil reserve.
D. The oil status of any supply zone drawing supply from the Australia box is determined by the number of oil counters consumed from the Australian oil reserve.
E. Western Allied naval units, including ASW, in the Atlantic and Pacific SW boxes are not subject to oil effects. Western Allied naval units in the Indian Ocean SW box, other than ASW and transports, require oil from the South African, Indian or Australian oil reserve.
33.472 WESTERN ALLIED OIL SOURCES: Each turn the various Western Allied oil reserves may obtain the indicated number of oil counters from the following sources if a supply line can be traced from that oil source to an unlimited supply source associated with the oil reserve in question:
33.4721 U.S. BOXES: Unlimited.

During the war, the United States produced nearly two-thirds of the world's oil supply. For the Western Allies, oil is not a question of production but rather a question of having the transports necessary to ship the oil to where it is needed.

33.4722 MOSUL: Three. These oil counters may only be used to meet the oil needs of the supply zone in which Mosul is located and the Mediterranean front portion of any supply zones tracing sea supply from that supply zone. One Mosul oil counter may be shipped to Russia through Turkey each turn if this is otherwise permitted (40.25, 40.6). Oil counters produced in Mosul may not be shipped in Indian Ocean transports.
33.4723 ABADAN AND AHWAZ: Three for each. The Western Allies may draw oil from the Persian oil fields if Persia is neutral or under Western Allied control, but may not draw oil from Persian oil fields controlled by Russia, the Axis or occupied by Persian partisans. Oil drawn from the Persian oil fields may only be used to meet the oil needs of units and hexes in Persia unless shipped out of Abadan in Indian Ocean transports. One Persian oil counter may be shipped to Russia through Persia each turn if the Persian route was opened in a previous turn and such shipments are otherwise permitted (40.25, 40.5).
33.4724 WESTERN ALLIED-CONTROLLED OIL CENTERS: Oil counters from Brunei, Palembang and Ploesti if they are under Western Allied control, but only to meet the oil needs of the supply zone in which the oil center is located.
33.473 ASSIGNING TRANSPORTS TO CARRY OIL: The Western Allies may ship oil during initial supply determination and post-combat supply determination by assigning one Atlantic, Pacific or Indian Ocean transport to sea escort each oil counter. The number of transports which may be assigned to sea escort oil each turn is half (round up) of the number of transports available in the SW box in question: 1 transport: 1 oil counter; 3 transports: 2 oil counters, 5 transports: 3 oil counters; 7 transports: 4 oil counters; and so on. Transports which are not assigned to sea escort oil may be used for other purposes.
33.4731 ATLANTIC:
A. There is no limit on the number of Western Allied Atlantic transports that may carry oil from the U.S. each turn, apart from that set out in 33.473.
B. Western Allied Atlantic transports may be used to ship oil from the Atlantic U.S. box to any eligible Western Allied controlled port or to the South Africa box.
33.4732 PACIFIC:
A. PREWAR OIL REQUIREMENTS: Prior to the outbreak of war between Japan and the Western Allies, three Western Allied Pacific transports must be assigned to carry oil counters, even though this has no effect on the Pearl Harbor, Australian and Manila oil reserves, which remain fixed at their initial levels until the outbreak of war between Japan and the Western Allies. Once the Western Allies are at war with Japan, this requirement does not apply.
B. PACIFIC OIL RESERVES: The U.S. may sea escort oil to the Pearl Harbor, Australian or Manila oil reserves from the Pacific U.S. box using Western Allied Pacific transports. Oil may not be shipped to these oil reserves through the Indian Ocean.
33.4733 INDIAN OCEAN:
A. USE OF INDIAN OCEAN TRANSPORTS: Indian Ocean transports may be used to ship oil counters:
B. INDIAN OIL CONSUMPTION: Prior to the outbreak of war between Britain and Japan, oil consumption in India is not tracked; but three Indian Ocean transports are inverted at the start of each Allied player turn to reflect the use of Indian Ocean transports to ship oil to India.
C. EUROPEAN SCENARIO: There is no requirement to ship oil to India in the European scenario. However, three Indian Ocean transports are inverted at the start of each Allied player turn to reflect the use of Indian Ocean transports to ship oil and units to India.
33.48 INITIAL WESTERN ALLIED OIL RESERVE: Until the start of the first Allied player turn following the fall of France, Western Allied oil consumption is not tracked and the Western Allied oil reserve is deemed to contain six oil counters.
33.49 CHINA EXEMPT FROM OIL EFFECTS: China and Chinese units, including the Flying Tigers, whether lent or not, are not subject to oil effects.

33.5 OIL CONSUMPTION:
33.51 USE OF OIL COUNTERS: Oil counters may be used by the moving player during his player turn to:
A. Offset one or more of the three service oil effects described in 33.61A-C (air, naval and army).
B. Use air and naval units beyond that allowed by offsetting the air and naval oil effects (33.71C, 33.72C).
C. Permit efficient use of major power construction limits (33.61D).
D. Trigger cumulative Japanese resistance modifiers for the control of island groups (33.74,57.14D-F).
E. Allow BRP base growth during a YSS (33.61E).
33.52 TIMING:
A. AIR, NAVAL AND ARMY OIL EFFECTS: Oil counters from oil reserves or local oil centers may be used to offset air, naval and army oil effects:
B. USE OF ADDITIONAL AIR AND NAVAL UNITS: Oil counters may be used at any time during either player turn to use additional air and naval units.
C. CONSTRUCTION: Oil counters may be used during the unit construction phase to offset construction oil effects.
D. JAPANESE RESISTANCE:Oil counters may be used at the end of a game turn to trigger cumulative Japanese resistance modifiers for the control of island groups.
E. BRP BASE GROWTH: Oil counters are used during the YSS to allow BRP base growth.
33.521 VOLUNTARILY INCURRING OIL EFFECTS: An alliance faction may voluntarily incur one or more oil effects in order to conserve oil.
33.53 OIL STATUS OF SUPPLIED AREAS:
33.531 DETERMINING OIL STATUS: The oil status of unlimited supply sources is determined prior to or during initial supply determination by the oil consumed from the oil reserve associated with the supply source (33.441, 33.451, 33.461, 33.471).
33.532 OIL IMPAIRMENT REFLECTED IN SUPPLY: If no oil effects are incurred by an unlimited supply source, the oil status of that supply source is unimpaired and the hexes and units supplied from that supply source are also unimpaired by oil effects (EXCEPTIONS: Supply zones receiving supply from the U.S. or South Africa boxes - 33.533). However, if one or more oil effects are incurred by an unlimited supply source, all hexes and units supplied from that unlimited supply source are similarly impaired.
33.533 SUPPLY ZONES DRAWING SUPPLY FROM THE U.S. OR SOUTH AFRICA BOXES: The oil status of supply zones containing ports which draw supply from the U.S. or South Africa boxes, and of other supply zones supplied from such supply zones, is determined by the number of oil counters consumed in that supply zone. The oil counters consumed may be taken from an oil center in the supply zone or shipped on transports through the relevant SW box to a port in the supply zone.
EXAMPLE: At the start of the Western Allied Spring 1943 player turn, the Western Allied European oil reserve contains four oil counters. The Western Allies have 22 transports available in the Atlantic SW box.
The Western Allies also have a Western Allied armor unit, a motorized infantry unit and three AAF in Morocco, having invaded Casablanca in a previous turn.
In Winter 1942, Britain and Northern Ireland were supplied from London; Casablanca was supplied directly from the U.S.
In the Western Allied Spring 1943 oil adjustment phase, the Western Allies use three oil counters from the Western Allied European oil reserve to offset the air, naval and army oil effects in Britain and Northern Ireland.
Western Allied units and hexes in Morocco retain the supply and oil status from the previous turn until initial supply determination of the Western Allied Spring 1943 player turn.
During initial supply determination, the Western Allies use six Atlantic transports to send oil to Britain. These oil counters are placed in the Western Allied European oil reserve.
The Western Allies again trace sea supply directly from the Atlantic U.S. box to Casablanca, using one Atlantic transport for the sea supply line. If the Western Allies wished to fully utilize their ground and air units in Morocco, they must also use one additional Atlantic transport to offset each relevant oil effect in Morocco (which does not have a local oil source). As the Western Allies have ground and air, but no naval, units in Morocco, two additional Atlantic transports would be required to ship oil to Casablanca to offset the air and army oil effects in Morocco.
Had sea supply been traced from Britain to Casablanca, the oil status of London would have determined the oil status of Casablanca, saving the Western Allies three Atlantic transports.

33.534 LOCAL OIL CONSUMPTION: Oil counters produced by a local oil center or shipped into a supply zone may be used to augment the supply traced into a supply zone, as well as supply traced from that supply zone into other supply zones.
EXAMPLE: The Western Allies trace a sea supply line from the South Africa box to Basra using one Indian Ocean transport. Mosul is undamaged and controlled by the Western Allies. The three oil counters produced by Mosul meet the oil requirements of the Middle Eastern supply zone. Other Indian Ocean transports could be used to ship additional oil counters to the Middle East if the Western Allies needed additional oil counters to conduct an offensive on the Mediterranean front in addition to the western front or if Mosul were damaged or under Axis control.
33.535 TIMING: A supply zone retains the supply and oil status of the previous player turn until the end of the initial supply determination segment of the current player turn (EXCEPTION: If an air, naval or army oil effect from the previous player turn is negated by the use of an oil counter during the oil adjustment phase of the current turn, air, naval or army operations are immediately restored to normal, prior to initial supply determination - 33.62). Naval units may patrol based on meeting the naval oil requirements for the previous turn, but patrols that remain in their patrol hexes during the combat phase must meet the naval oil requirements for the current turn.
33.54 OIL STATUS OF UNITS:
33.541 DURATION: Oil counters used to offset air, naval and army oil effects (33.51A) and to allow for the use of additional air and naval units (33.51B) have effect until the end of the initial supply determination phase of the friendly player turn following their use. Air and naval units used in the movement phase of their player turn, prior to or during the initial supply determination phase, count against the limit on air and naval factors used for that player turn, so the use of other air and naval units after the initial supply determination phase may require the use of additional oil counters.
33.55 BRITISH AND AMERICAN OIL USE DISTINCT:
33.551 British and American air, naval and army oil requirements are distinct and each British and American service branch requires its own oil supply.
A. Oil used for British service requirements covers Commonwealth, Free French and British minor country units.
B. Oil used for American service requirements covers American minor country units and Australian units in the Pacific theater.


33.6 OIL EFFECTS:
33.61 OIL EFFECTS: During his player turn, as set out in 33.52, the moving player determines which, if any, of the four oil effects set out below he wishes to offset. Oil effects apply to all members of an alliance faction within the affected supply zones (EXCEPTION: British and American oil requirements are distinct - 33.55). The effects are:

A. AIR: One oil counter is required to offset the general air oil effect. This eliminates the air oil effects for all army air units, including associated and allied minor country AAF, naval air units, air transports and jets, other than those engaged in strategic warfare or flying BRPs over the Hump to China. Whether or not the general air oil effect is offset, additional oil is required to offset the air oil effect for strategic bombers, interceptors, AAF and jets to conduct or oppose strategic bombing or flying bomb attacks or to use an air transport to fly BRPs over the Hump to China (33.71D). Kamikazes do not require oil. If the air oil effects apply:


B. NAVAL: One oil counter is required to offset the general naval oil effect (subject to 33.72B in the Pacific theater). This eliminates the naval oil effects for all slow ships, light ships, two- and three-factor capital ships, CVLs and submarines. Whether or not the general naval oil effect is offset, additional oil is required to use larger fast ships (33.72D). If naval oil effects apply:


C. ARMY:One oil counter is required to offset the army oil effects.

The air, naval and army oil effects have the same effect on air, naval and ground units as partial supply (30.52). Oil effects are not cumulative with the effects of partial supply.

D. CONSTRUCTION: Construction at normal construction costs requires the expenditure of oil counters. Subject to overall construction limits: the affected alliance faction may build up to 25 BRPs of units at normal construction costs if one oil counter is expended; up to 50 BRPs if two oil counters are expended; up to 75 BRPs if three oil counters are expended, and so on (27.35). Additional units are built at double the normal construction cost (27.13B; see also 27.14). A major power is considered to have incurred the construction oil effect if its alliance faction does not spend at least one oil counter to allow up to 25 BRPs of builds at normal construction cost.
E. ECONOMIC: There is no economic oil effect during game turns. During the YSS, one oil counter must be used for every 25 BRPs of base growth. (EXCEPTION: China, which is not subject to oil effects - 33.49). Partial oil counters may be used (33.81D). Oil reserves do not affect major power BRP growth rates.
33.62 RESTORATION OF OIL SUPPLIES TO ARMED FORCES: If the air, naval and army oil effects are negated, air, naval and army operations are immediately restored to normal.
33.63 APPLICATION OF CONSTRUCTION EFFECTS: Construction oil effects are determined by the oil status of any supply zone in that major power's home country which contains an unlimited supply source or, for Britain, which traces sea supply from the Atlantic U.S. box, as designated by the owning player. No other supply zones need to offset construction oil effects. Construction oil effects do not apply to Britain if all hexes in Britain are isolated or under Axis control.

33.7 USE OF OIL FOR AIR AND NAVAL OPERATIONS:
33.71 OIL REQUIREMENTS FOR AIR OPERATIONS: Oil counters are required for air operations as follows:
A. AIR OPERATIONS PROHIBITED: If air oil effects are not offset, air operations are restricted as set out in 33.61A.
B. COST OF OFFSETTING THE GENERAL AIR OIL EFFECT: One oil counter is required to offset the general air oil effect.
C. EFFECTS: If the general air oil effect is offset, air oil effects do not apply to the alliance faction’s AAF, including associated and allied minor country AAF, naval air units, air transports and jets, other than those engaged in strategic warfare or flying BRPs over the Hump to China, and these air units may conduct air operations during both the owning major power’s player turn and the opposing player’s turn.
D. STRATEGIC WARFARE AND FLYING THE HUMP:: Whether or not an alliance faction has offset the general air oil effect, it may use oil to offset the air oil effect for air units engaged in strategic warfare and flying BRPs over the Hump to China:
33.72 OIL REQUIREMENTS FOR NAVAL OPERATIONS: Oil counters are required for naval operations as follows:
A. NAVAL OPERATIONS PROHIBITED: If the general naval oil effect is not offset, naval operations are restricted as set out in 33.61B.
B. EFFECTS: If the general naval oil effect is offset, the naval oil effects do not apply to slow ships, light ships, 2- and 3-factor capital ships and CVLs, and these naval units may conduct naval operations during both the owning major power's player turn and the opposing player's turn.
C. ADDITIONAL NAVAL UNITS: Whether or not an alliance faction has offset the general naval oil effect, it may use oil to offset the naval oil effect for additional naval units as follows:
D. SUBMARINES: Offsetting the naval oil effect covers all submarine use. If the naval oil effect is not offset, oil may be used to allow submarine use, with one partial oil counter being required for every five submarine factors, rounded up (33.82B).
E. SW BOXES: Naval units based in SW boxes are not counted towards oil use, even if used for naval activities on the mapboard.
33.73 MECHANICS:
A. TIMING: Oil counters used for additional air or naval operations are consumed when the air or naval operation is conducted.
B. SOURCE: Oil counters used for additional air or naval operations are subject to the same restrictions and transport requirements as the oil counters initially used to offset the air or naval oil effect. The use of these additional oil counters may not be intercepted or opposed.
C. COMBAT: Air and naval units that engage in combat are not required to use oil, but incur a -1 Air or Naval Nationality DRM in combat if they do not (33.61A, B,).
33.74 ISLAND GROUPS: Each cumulative Japanese resistance modifier from island group control (57.14 D-F) costs the side that benefits one oil counter per modifier:
33.8 PARTIAL OIL COUNTERS:
33.81 PARTIAL OIL COUNTERS: Each alliance faction may use one or more partial oil counters to maximize oil efficiency, for some or all of the following purposes. Each oil counter converts to five partial oil counters. Partial oil counters may be used for these purposes whether or not the air, naval and construction effects have been offset.
A. AIR: To allow air units to conduct strategic bombing or oppose strategic bombing or flying bomb attacks or allow an air transport to fly BRPs over the Hump to China.
B. NAVAL: To allow fast 4- and 5-factor battleships, CVs, CVBs and submarines to be used.
C. CONSTRUCTION: To allow additional units to be constructed at the normal BRP cost.
D. BRP BASE GROWTH: To allow BRP base growth during a YSS.
33.82 INCREMENTS OF FIVE: Each partial oil counter represents one fifth of an oil counter and allows:
A. AIR: The use of five air factors to conduct or oppose strategic bombing or flying bomb attacks, or to fly BRPs over the Hump to China (one partial oil counter: 5 air factors; two partial oil counters: 10 air factors; and so on).
B. NAVAL: The use of one 4- or 5-factor battleship, CV, CVB or submarines (one partial oil counter: one ship or one to five submarine factors; two partial oil counters: two ships or six to ten five submarine factors; and so on).
C. CONSTRUCTION: The construction of 5 BRPs of units at the normal BRP cost (one partial oil counter: 5 BRPs of units; two partial oil counters: 10 BRPs of units; and so on).
D. BRP BASE GROWTH: BRP base growth of 5 BRPs (one partial oil counter: 5 BRPs of growth; two partial oil counters: 10 BRPs of growth; and so on).
33.83 RETENTION: Unused portions of a partial oil counter may be retained for future use. An alliance faction may never retain more than 80% of an oil counter, because anything greater than that would be consolidated into a full oil counter.

33.9 UNINVERSION OF AIR AND NAVAL UNITS:
33.91 Air and naval units do not require oil to uninvert. See 18.7 for the uninversion of air units and 21.7 for the uninversion of naval units.
