Never have dated a Marine...but I have uncles left and right from every branch of the armed services except for the Coast Guard!
However not sure this guy's story...his profile says Dad-Marines, Mom-Navy. Then under his favorite things he lists Marines, and he is wearing a MARINES shirt in a pic or two on his profile. However know he does some sort of software/technology job. The word CISCO was in there somewhere--see I am so NOT a techie!
Hopefully the respect side of the military will carry over...
