Probably the most neglected theater of WWII games because there wasn't any major huge decisive victories but I think a handful of maps taking place in China would be interesting.  Perhaps a three way battle between Nationalists, Communists, and the Japanese.   Shanghai for example was pretty much the Stalingrad of the Orient.  Some new weapons that could be introduced would be the Chiang Kai-shek and Hanyang 88 rifles Mauser C96 pistols and the Dadao for melee combat.   I think it would be interesting having a battle that relied on brutal close quarter and melee combat with the Dadao being used against the Japanese Shin guntō  as neither side had sub machine-guns available.  (and yes I know about the type 100 but is was pretty rare on the battlefield and not used till later in the war)

So what one could have is a close quarters battle with bolt action rifles, pistols, and powerful melee weapons along with APCs as support to give more dynamics to the mod.   Now I know something like this would be along time coming because the Japanese are not even in the mod yet but  I think it would be interesting and something to add while doing up the pacific maps.   It would also add a change of scenery outside jungles and islands for the Japanese.  What do you all think?  

p.s.  I added a clip from a Chinese WWII film to give some sort of example  http://www.youtube.com/watch?v=ZuBDZkyrMhI
