Panzer means TANK. Therefore Panzerschreck means tank fright and Panzer Soldat is Tank Soldier. The name tank soldier is reminiscient of the giant robot. In a scene of the opening cinematic the giant robot has "claws." If you are unlucky to get away from the robot, the robot will pick you up with it's "claws." ... and that is why firetrucks are red.
