like Japan, Italy buys Infantry at Capital for 2 IPC each already
so it would also be the “3 INF for 5 IPC” deal instead
having said that, I think 2 IPC INF is pretty cheap already
Germany’s “once per turn per IC” could be changed as Italy takes one IC.
US’s “once per turn per IC” could be changed as it would be funny with captured ICs…say in East Indices.
Germany (VII Submarine) = Once per turn, up to 2 SS can be purchased and placed in Germany for 6 IPC each provided no surface naval units are purchased there.
US (Essex Carrier) = Once per turn, 1 CV can be purchased and placed in Eastern United States or Western United States for 14 IPC.
