They can also conduct strategic bombing on an anti-aircraft gun. Bombers can also be used to perform airdrops over friendly areas. In this fashion a country can assign a number of IPCs to a specific bomber. This takes some risk so a die is rolled to determine if the air drop was a succes or not. For fighters things only chaned for Japan.
Japanese fighters can perform kamikaze missions.
The industrial complexes that are purchased during the game have limited and restricted production. The production is 'restricted' in the sense that the type of units an industrial complex is able to produce is also related to the IPC-value of the area. If IPC-value of the area is only a single IPC only infantry units can be produced in the factory. Finally, if the IPC-value is 3 armor and transports are added to the types of units the factory is able to produce. The new Weapon Development Chart includes a technolgy called Industrial Growth.
