Ideas how to improve WinSP MBT/WW2 !

[Imp]

But the real question is...
Just what sort Chinese force will make the scenario challenging?
So if you want to come up with a set of Chinese forces for this I'd be overjoyed to play!

The Chinese have recently spent a lot on landing ships etc & their marines so perhaps marine vs marine. Chinese Marines from memory have an AFV similar to BMP-3 & a Amphib light tank based on it, obviously as Marines most would not have the aformentioned. While not in the game also believe they have an amphib version of SPSAM AA gun combo though for what you suggest probably still mainly MANPADS for AAA. Also seem to remember they have several light tanks APCs IFVs to choose from for follow on force. Also have a good range of light mortars etc till main arty can be landed. Biggest failing is probably air there EW suites are not very good on the whole & AAA overall lags behind the main players so USMC could have a bit of fun if area stuff is not in place.
