I was wondering you plan to release a version compatable with the ACE mod? The ACE menu does not support SupportCall.
By the way, I think your mod is great. One of my biggest complaints about ARMA 2 was there was almost no variation on the loadouts. I was always stuck doing most of the missions as a rifleman and I could never play as a designated marksman or a machinegunner. Also, I love how I can finally play with mod added weapons without hassle.
