Colt 45's/Thompson submachine guns?
Just one quibble. The Norwegian commandos are being run by British SOE circa 1943. Yet they seem to be exclusively equipped with Colt 1911 pistols and Thompson submachine guns.
That doesn't seem to be the right mix. Sten guns would be more like it.
Also, there's a lot of two-handed grip action involving the Colt 1911's. I believe back then only a one-handed grip was taught.
