Actually i hate the Schreck :< Cant see shit with that shield up all the time ..
My vote goes for the PIAT (PerfectIncredibleAwesomeThing) for being able to one shot King Tigers, for being able to kill people half way across the map because of the amazing ballistics, for being the perfect grass ninja weapon, for having more ammo than other AT weapons, for being the only true Lumberjack Commando weapon ..
