WHy in ALPHA +2 are there 11 German infantry in Germany?
There was some concensus among LH and those playtesting Alpha +1 that Germany was underpowered in the land attack into Russia and ran out of steam before capturing the victory cities more often than not or attaining economic parity (also why Germany and Italy got more NOs). The desire was to provide some additional land units that could keep up some momentum.
can they build a Minor IC then upgrade it to a Major IC, since the rules do not state anything about upgrading it to a Major IC.
Upgrading a minor to major on foreign soil still counts as building a major, so with the new rules Korea is the only location Japan can build a major anywhere in the world.
