Tatoo
From the ROTC orientation a few weeks ago---don't know which program you are talking about. In the Corps of Cadets program, at most universities, a student is forbidden from getting ANY tatoos while they are a cadet. Again, not sure about all of them. As far as the ROTC in general, I can only speak for the Navy and Marine Corps. Their advice was this:
If you have them, they must be above the short sleeve shirt. If you don't have them don't get them. They said they are getting strict with the tatoos. I have heard from several people that having a tatoo can limit what you do as an officer AND- this is a big one-the military could change their policy regarding tatoos at any time. I was told, or my son was told, by many highly enlisted--e8/e9 and officers, the tatoo thing was a very bad idea.
Something to think about-is it worth it?
