I really wish HTC would remodel the current M3/M16 and bring forth about 5 or so of the different models used in WWII. There were M3's used in anti-tank roles(76mmAP), infantry support roles (105mmHE) , supply (AH's current M3), anti-aircraft (AH's current M16), etc etc.
One would like to believe that it would be one of the easiest things to model for the game: the only real difference between the models were the cargo bay area and the corresponding weapons platform (or none). It would be the easiest way to add variety to the sim/game. BAM! We have 5 new gv's to tinker with.
