FWIW, I've learned the hard way, many times, that some folks present themselves as something they aren't, and claim experiences they haven't had, to boost their perceived prestige. This gentleman may well be everything that is claimed and more, but then again, it's wise to assess the validity of people's claims before accepting them at face value.
No offense to anyone intended, have just dealt with countless proven posers claiming to have been snipers, Special Forces, SEALS, Prisoners of War, Combat veterans, Combat Wounded, Huey Door Gunners, fake veterans, etc. ad nauseum. Stolen Valor cases are surprisingly common, and not limited to just the military.
I don't think Jim Cirillo, Jelly Bryce, etc. carried guns stashed all over their bodies despite having won MANY gunfights. Extreme behavior or highly-unusual claims are often reasons to raise your BS-detector to High Alert, until claims can be verified. Of course, individual differences DO exist, just don't automatically believe everything you hear!
