Would it be possible to make tanks and apc's take falling damage. It is possible to ramp the M113 down a bank on Kolgujev and the vehicle doesn't take damage. The M113 might land on its side making it useless, but it still doesn't get damaged. Thats the only problem I can think of that hasn't been listed above.
Possible Additions:
I believe there should be the option to redeploy the M2 somehow.
A deployable mortar, similair to the ones used in veitnam.
Artillery!!! Especially usefull if they could fire smoke shells into an area before you engage.
Proper A.P. mines, the ones that ppl in the community have made are nice, but not ideal
Maybe if you can't add these to OPFlash you could add them to OPFlash 2 hehehe.
One of my friends purchased Il2 Sturmovich and he was trying to describe how good it was over the phone. Eventually the best description of it was, "Well I'm calling Il2 Flashplane from now on.". Now if thats not a compliment I dont know what is.
