Ill get straight to the point, I hate the cumilative affect of a load of infantry potshots on your vehicle example: your looking for an enemy soldier with an at-st after a while you kill him but hes knocked a few hp off you in the time it took to kill him. This happens all the time in maps like tatooine mos espa so your vehicle is pretty much wrecked by the time you get near a serious fight so, I say you need a certain number of laser shots to hit a vehicle at once to cause damage, more shots than for example than a single soldier can fire, maybe you need 2 or 3 people to attack at the same time.
                                   Another possiblity is that vehicles automaticaly recover the damage they suffer from small arms fire but will not recover without repairs from say a rocket or a heavy laser blast. I know you guys are getting flooded with requests right now but I hope you consider this.
