The captured SS officer's uniform is the famous black uniform worn by the SS in the 1930s. These uniforms were discontinued in 1939 before the war began and the SS switched to field gray like the Heer (Army). The British soldiers refer to him as "Hauptsturmführer" (captain) and his rank is that of an Obersturmbannführer (lieutenant colonel). This is addressed when the SS officer is first captured. One of the men say he's probably upset about not being called by his correct rank.
When raiding the pillbox at the end of the movie, the German machine guns are MG-42s, but the sound effect used is that of a Browning .50 caliber M2. The MG-42 has a much higher rate of fire and does not have a distinctive metallic sound when the bolt cycles like the sound used.
The weapons used are incorrect for the British Army of the film's period. The 1928 Thompson was used at that time, but a folding M1 carbine was not. The American paratrooper would have carried that. The M1 rifle was American, but the British rifle should have been the SMLE (Mk whatever). The American soldier carries an M3a1 Grease gun, but is not shown carrying extra mags. What he does have are M1 en-bloc clips on his suspenders. Why?
During shooting scenes with the M1, the bolt never moves. The 1928 Thompson fires with an open bolt, yet in combat scenes is always shown closed, a common error in films of this type.
The factual listing above states that the machine gun in the pill box was an MG-42. Not so. It is an MG-34. This is obvious by looking at the machined, round barrel shroud vs. the stamped, more square metal shroud for the 42. As such the fire rate is correct for an MG-34. The MG-34 was much slower.
