The round German tent is shown exploding into a ball of fire twice.
In the opening scene when Tully and Moffitt come flying over the dune, you can see Tully's helmet fly off and roll in the sand. In the next few scenes you can see his helmet reappear and disappear several times.
The patrol is surrounded at the pass. They attach large speakers to the jeep and play a recording of Sherman tanks to make the Germans think they are under attack. The issue is, where did these speakers come from and where did they go? When the Germans leave the pass the speakers are gone and you can see that they are not in the jeeps.
