Everybody and their dog wears camo or some kind of military gear. You can buy the uniform at any Army/Navy store along with a chest full of medals to put on it. Who you normally don’t see a lot of wearing this stuff is ‘veterans’. I have a ballcap with my unit embroidered on it, my granddaughter wore it when I took her to my brigade reunion, with my blessing. At 16 she turned a few Ranger trainees heads at Benning lol.
A ball cap honoring a unit, or “military” camp is one thing. To adopt the full military regalia of a legitimate veteran while never having served is stolen valor, and worthy only of opprobrium.
