And the 8th Air Force lost more men flying bombing missions over Germany than the Marine Corps lost in the whole war.
Merchant sailors suffered an even higher casualty rate. You were more likely to die as a sailor in the Merchant Navy than you were in any of the armed forces branches, although for years they were denied the right to take part in war commemorations (in Britain at least) because they were considered ‘civilians’. They were probably some of the most unappreciated participants in the entire war effort.
