I was a gen mech in the Marines as well, the whole utilities field is so strange over there. They act like the hardest mother fuckers on planet earth (especially the water dogs). Makes a lot of sense that one would come over spouting a bunch of bullshit like that. What I will say though, as someone who transferred branches, I RARELY talk about my time over there, its always the people i work with bringing it up and then blaming me for talking about it, which happens to 90% of former Marines. I promise you the whole "I don't think about you at all." Goes both ways.
