Well, without a doubt... I would join the US Marines as a grunt.
Flying flight sims may be my bag (I don't play games like Tribes because shooting human like figures gives me night mares.) But deep down in my chest beats the heart of a grunt. I was on the ground in Vietnam, Con Thien, Cam Lo, GioLinh, Rockpile, Dong Ha, Alpha 1.
I would help kick the Japs prettythang all the way back to Japan, alongside of my Dad (a US SeaBee).
If I couldn't be a Marine, then I'd be a US Dogface, and kick those slimeball Nazis prettythangses back to hell.
I am mostly of German heritage [and a lot is &@#! Prussian
], I may have the heritage, but Nazis are the scum of the earth.
Yep, killing Japs or Krauts on the ground, no doubt about it.
Your mileage may vary...
