I don't know if I'm the only one who enjoys zooming around in a jeep resupplying GV's and driving 3 troops in to aid an M3, but I think that adding smoke to their load out would be beneficial in helping the jeep go around without being shot as much. I know people are going to say how is the smoke deployed or something like that so I'll simply say the driver throws it or the guy riding shot gun does (or even the gunner).
