This uniform combination caught my eye.
The Field Jacket is primarily worn to simulate the Dress Blue jacket. The field jacket’s rough similarities to the blues coat allow a Marine to place the formal uniform’s belt at the right height to practice fixing and unfixing a bayonet to his M1 Garand rifle.
The USMC must be really hurting for adequate funding. In an age when the M14, M16 and M4 carbine have become standard, these guys are still issued WWII-era M1 rifles???
