To my knowledge the Jeep Commando was never used by any branch of the US service, nor by any foreign military either. It's probably just a hobbyist who had a Commando, and painted it to "play the role". Like the guys who paint CJ-2As and CJ-3As to portray a M38, or those who use their CJ-5s to play M38A1s. Not authentic, would never win a judging contest, but they are still fun, so who are we to judge?
I believe you are absolutely right.
That model of Commando (short hood) was manufactured from about 1967 to 1971. I've owned 2 of them and still have one in pieces parked behind my MKT-85 trailer. I'm at the wrong computer or I'd add some pictures of mine, but here's one I Googled.
A Commando was basically a modified CJ-5. The frame and powertrains were identical and the tub was a throwback to the Jeepster of the late '40s. It had a different hood and short wings welded onto the grill to widen it and the turn signals were moved out onto the wings. Title said "Jeepster Commando", so I got a cheaper insurance rate.
The really interesting thing about it was that they bought a 225 CUID V6 from Buick known as the "Oddfire V6" because the cylinders were 90 degrees apart like a V8. It fired 3 times 90 degrees apart, skipped a beat fired 3 more times and skipped another beat. It had a MONSTER flywheel to carry it through. The 1978 Buick 232 was the last Oddfire V6.
In 1972 they stretched the nose (UGLY!!) and put an AMC V8 in it. That model only lasted 2 r 3 more years. During the early years they make a short cab and put a partition behind the front seat, making it a short bed pickup. It looked like a 4 wheel drive Ranchero. I have both tops for mine.
