When I was in the Navy when you received a chevron you got what is called "Frocked" by everyone senior to you in your squadron or command. Meaning a free shot "punch" in your right shoulder. Some guys would not hold back, I know I didn't. By the end of the day you could not move your right arm at all. LOL.
I personally think that what he is doing is disrespectful to the men and women who have served.
