USMC Pin-iT Card enlisted collar devices http://pinitcard.com

Camouflage Shirt? Khaki shirt? Collar device? you weren't a Marine were you? lol By the way one of the few things I never measured when I put it on a uniform was a set of Chevrons on my utes. Might take a sharpie to them if they were too chipped but all eye ball no measuring. Now a set of chucks or alphas etc.. then you are measuring.

Nice, but 30 years too late!
We did use a match for distance of ribbons to top of pocket.

Two half inch wide strips of tape works fine
