The bit where the americans are cut up by that AA gun on Saving Private Ryan.

In Enemy at the Gates, the russians being machine gunned by the german planes, though could be better, the dive-bomber used much larger bullets...

The bit where the german gets shot in the leg and ran over in Band of Brothers, a big shock, espically when you got girls in the room seeing it for the first time - what a way to go.

In Cross of Iron, during the first battle when the russians are retreating, a MG42/34 cuts up the mud and brings down several russians, something about machine guns...

In Stalingard, the part where the two germans run into the building and set of a demo-charge, engulfing four machine guns in flames, booooom!
