After playing with the photo on my Mac, I think (90% sure) that the gent in question has very large MS shoulder boards. When I magnified and cleaned up the image, I could distinctly make out what looked to be the first 1/2 of a letter M (possibly N). Also, if the shoulder boards were as long as they look (to me) then te MS would be centered on them. It looks like the fellow had very narrow shoulders with very big straps.
