I would say yes, I would eye you with a bit of suspicion, being an former marine. I mean you may start a conversation with some hardass marine combat vet in the john. I know you would get looks. Me(ie.me a former MOS:5811 military police aka military piggie) and my best friend(ie.he's a former MP/ 4th force recon marine team leader/current 0-5 USA Res. Lt Col), who are both gulf war era vets(1990-1991), he is a iraq combat vet(2007), would eye somebody wearing part of a uniform and really look and see what's that all about. Other than that, nope. Just the clothing.
Lucia,
Just saying, since my friend, tells me all sorts of scuttlebutt from the military, and knows I"m trans, and he does not want to accept it(ie.its on him),oh well.
