National Units:
Russia= Once per turn Russia may purchase 2 armor units and place them in Moscow for a total of 8 IPCs.
Germany= For every IC where no surface naval units are built in a given turn, 1 sub may be built there for 6 IPCs.
(From Wikipedia: Having no hope of defeating the vastly superior Royal Navy decisively in a surface battle, the German High Command immediately stopped all construction on capital surface ships save the nearly completed Bismarck class battleships and two cruisers and switched the resources to submarines, which could be built more quickly. Though it took most of 1940 to expand the production facilities and get the mass production started, more than a thousand submarines were built by the end of the war.)
UK= All fighters purchased and placed in London cost 8 IPCs. All UK fighters get +1 defense in London.
Japan= Once per turn Japan may purchase 3 infantry units and place them in Tokyo for a total of 7 IPCs. For every combat where Japan is defending a yellow territory with at least 1 infantry, 1 (and only 1) infantry defend at a 3.
(This is to represent all of the following: Japanese Warrior Code, Banzai attacks (ironically used on defense), dug-in defenders and Japanese jungle warfare.)
US= All US aircraft carriers cost 14 and move 3 in the non-combat move phase.
(Essex carriers were rushed into production and they were fast.)
This is pretty balanced…
Russian, UK, US advantages worth about 1.5+2.5+1.5 (per turn, respectively) = 5.5
German and Japanese advantages worth about 3+2.5 = 5.5
+++++++this is more like it! add this to the draft.
