UPDATE: Barney added to this discussion. He had a customer who refurbed a military DJ-5.

Note that it is left hand drive.  He said they were used for base runabouts – messengers, delivery, etc. Obviously the graphics are not original but a tribute to his own service with the Corps.

I know the military used CJ5s stateside in the 70s and 80s and even in civilian colors as if they had got it from a dealership. Saw a 73 CJ that was and  metallic green with a white Meyers hard top   and a blue cherry on top as it was an MP Jeep at Fort Ord CA. I saw it patrolling the Naval Post Graduate School in Monterey”

============================

Chris was kind enough to share images of his DJ-5 that was purchased my the military. It just shows that the AM General DJ-5s were used by more than just the USPS.
