The German Panzerschreck is a copy of the bazooka. It has the ability to kill any vehicle or person in the game. They used to be very easy to kill and they had poor accuracy, but patch 2.2.6i upgraded them, making them very dangerous as their accuracy was increased. A nasty weapon.
In real life Panzerschrecks have a metal shield that protects the operator, but it is heavy, so it was coded so the Germans did not have the shields. Also there are three variants of the Raketenpanzerbuchse but only one variant is in the game.
