I'll inject some disrespect then.
In forums frequented largely by actual serving military members, the term 'Walt' has come into play. Generally they look like the gentleman in the foreground:
Walt is short for "Walter Mitty", but he also answers to 'wannabe'. You can find him on Airsoft bulletin boards, or message boards like this:

Pretending to be something he's not. You can generally tell he's not really a serving soldier by his use of all the correct slang, with just a titch too much "gung ho" thrown in for verisimilitude.
I don't have a hard time believing someone could blow off another human being's arm with a .50 and then go on the internet and laugh about it, but such a thing would have to be pretty rare indeed.
If Cipher is the real deal, well, my apologies, but you don't need to go on as if you're John Wayne. Certainly we don't need the offensive racial epithets here. It's mostly a civilian crowd.
The real combat veterans that have posted here in the past - Forever Babra, Desdichado, Nidan1 - have been pretty reserved about their experiences which is what one expects of a combat veteran. That's something most Walts don't get.
Again, apologies to Cipher if he is the real deal, but of course all we have to judge anyone on here is what they say and how they say it. Knowing all the right slang doesn't prove anything one way or the other.
Rant off.
