More modularity in the vehicles. I understand this has the ability to make things unrealistic with a quickness (Leo 2 with RWS mounted TOW and twin 120mm's would not be the intent here) but if done with the right options for each vehicle it could produce some amazing simulation. Could also cut down on model sizes instead of doing each model, have a baseline then discreet packages for upgrades. For example: In mission editor would select M1 Abrams, then be given options for upgrades: M1A1, M1A1 AIM, M1A1 AIM SA, M1A2 SEP, etc. All of these options could then be fitted with TUSK, plow, rollers, SLAT armor, CROWS, etc. The GUI could also work in vehicle/crew paint/camo schemes to be variable for each vehicle/unit. Apoligies for the yankee references, I know y'all love the tanks of the Vaterland but I try to speak on what I know.
