First, I think the game is great and I realize its geared toward aircraft.
...but the ability to cover your gv w/ foliage, thus making said GV more difficult to spot, would rule. Maybe it'd only last a specified time.....or could only be done in specific areas, or w/ specific models....or a jeep could carry netting out to locations...maybe this ability could be chosen in lieu of some ammo...btw, could a WWII era tank really carry 75 shells? Seems like alot but I wouldn't know. And hey, speaking of shells, would anti-personel or anti-aircraft "beehive" type loads be historically appropriate?
Would that be pushing it?
