Mine is a 76, and was Army. But, I served in the Air Force during those years, and these things were running all over the base. The Security Police ran them, and those were either Olive Drab, or Air Force Strata Blue with yellow stenciled markings. Most of them that ran on the flight line where I was most the time were the Strata Blue. I was an aircraft electrician and drove a strata blue IH step van as most of the aircraft maintenance trucks were, but the cops out there drove Jeep CJs or M880s in strata blue. That said, I plan on painting mine in Air Force Stata Blue with the yellow stenciled markings.
