I'm a vet, but I'm not a "tough guy"...I got out of the Army in 1980 and wore my combat boots, fatigue pants, and khaki shirts along with civilian clothes to save money. I was enrolled in a Biology course that included a dissection lab. To save a few bucks, rather than buying a lab coat, I wore one of my old fatigue shirts instead. I was in the hall one day taking a break when one of the ROTC students walked by and did a double take when he saw me. He then came back and told me that I needed to take the patches and name tapes off of my shirt. I told him that he was more than welcomed to try and take the patches, and/or the shirt off of me whenever he was ready. He left the area quickly, and afterwards, always cut a pretty wide path around me.
Regards,
Dave
