Guerilla
*you need two hits to take down a US land unit
US Aid incentives
*US may call up X INF for 1 IPC each, they only last til end of combat
Chinese resistance
*territory becomes to US control if unoccupied
Yes in the map those are not really US infantry but chinese infantry under control of the US player. The US only had the flying tigers and advisors in china.i could go with this: If your using national victory conditions then allow the US player to place 1-2 ( not sure which) chinese infantry (costing 2 IPC each) in each chinese controlled territory per turn.
I really like the idea that you must garrison the territory is you want to control it. Id say to gain the IPC you need to garrison with a land piece.
In fact i like the idea of garrison for all enemy controlled territory, but i feel this will hurt the axis too much. what you think?
