There are three close-ups of three different executions of spies. They were shot with M1 Garands and that means the much bigger
.308 30-06 M2 ball round rather than the smaller .223 that was used in the New Zealand shooting and we are told is fake because we don’t see fountains of blood pouring out of the bodies.
Times to watch: 3:44, 4:30 and 4:56. Do notice in some scenes the pieces of wood coming off the beam.
In other news, in one squad, there were several soldiers that missed on purpose. The other squad didn’t seem to mind executing the Nazis much.
