Air Force Use
With the use of the USAAF for massed daylight bombing raids over occupied Europe during World War II, flak protection against German anti-aircraft fire was developed. The first derivation of the M1 was to provide cut-outs so that it would fit over the earphones of the flying helmet. When extra metal plates were added to cover the earphones, the result was the M3. Larger ear plates and no flared lip to the helmet gave the M5.
