It must be true - it's in a movie ..........................
Tried watching a similar cr@p movie on Prime over Christmas.
A group of GI's, in Normandy - armed with an assortment of 'civvy' weapons, including a Winchester - repeated firing without once cocking the weapons, plastic helmets from a toy store, mixed personal equipment and atrocious field craft.
Gave up when a German sniper opened up with a fully automatic bolt action hunting rifle, and he was dressed in a mix of black SS and Panzer uniform, sitting in full view on a tree branch !
