chose the kit that situation requires, also, don't strike and armor from the same spot twice, if you see an attack chopper, better hide then you can attack it from bahind or scape,
2 days a go i was playing in sharqy as sniper, and i had 20 kills and 0 deaths, and we were kicking the mec's butt big time, none of the enemies realized from where i was shooting at (it was a really obvious place thoug) but then i got killed by a tank, cuase an assaul guy saw all the kills i was getting, and he wanted to kill some too, so he ran and went prone next to me but l the tank didn't saw us at first, but then this braind dead noob started to shoot at the tank with the g3 (tank got us with a shell)
so what i mean with this is, don't stan so close to teammates cause that make you a better target, for tanks,arty and noob tubers, also he can give away your position (like what happened to me)
also you can stay alive the whole round but not kill much, so vehicules are better for big kills strikes
