 So, the jacket that I'm wearing is the M65 Fuel Jacket Tri-Color that we wear here at the Barracks. So, the reason why we wear the Fuel Jacket in the service uniform is the jacket allows us to mimic the blues blouse. It allows us to get as close as we can to wearing a blues jacket without actually wearing a blues jacket to prepare us for the praise that we do here at the Barracks. So, just another little piece of Marine Corps history that we here at the Barracks still get to use that's not really used everywhere else in the Marine Corps, so still the keepers of tradition.
