Thanks for the thoughts. Wirestripper responded as well, and now I'm not sure if I will order one or not. The last thing I want to do is upset a veteran!
I have some vet friends that do get offended when they find these sorts of things. Why take the chance? A unit hat usually will prompt a question from a former serviceman, and if you feel comfortable answering the question, then fine. But, I would not wear a Navy hat, as I am army and vice versa. It is a pride thing, and the huge number of lying sacks of -----that say they were in Nam and served when they did not have spoiled many attitudes.
This used to be an issue with me as a former frogman (SEAL). We used to get upset when folks wore t-shirts and hats with the SEAL "Trident" logo on them. That's all passe. Now we just assume that anyone wearing the logo is a supporter or friend or familiy member.
Go for it, wear it with pride, they are "your team!"
