NASA seals are pansies.
The real unknown tough guys are guys like me: Screen-door gunners on nuclear submarines. I mean, what the f*ck are those space cowboys going to be shooting at up there? It is a total suck job with no tactical skill required.
Now when it comes to being a screen door gunner on a submarine, you got your terrorists, your enemy ships, enemy subs, sea monsters, and whales that try to mate with your boat to contend with. THAT is some hardcore combat right there. If the NASA seals saw something like a Kracken out in space, the pussies would run away and call the Airforce to deal with it.
Not so in my outfit. Once when my weapon jammed I had to take one on using only the issue bayonet while one of my arms was caught in the tread of the submarine because I was repairing it. I still have scars from that fight.
Not to mention the NASA seals would be useless on earth, whereas the US government sent me out to Afghanistan in 1988 to be a Navy Seal drill sergeant to teach their snipers. I was in several engagements and won the silver heart and purple star for my heroism.
