While driving the jeep, Tully takes off his goggles at 2:13. When the scene changes, he takes them off again at 2:19.
The Rat Patrol raid the fake munitions depot. No German is shot outside the doorway. When the hand grenade is thrown inside, there is now a dead German in the doorway. After the raid, the Rat Patrol survey the scene, and the German is no longer lying dead in the entrance. It should also be noted that the extra playing the dead German flinches just before the explosion.
