In the T2K games I played, my character tended to be a low rank person. I think PFC was the best I ever had. Being that I had no military experience, I would follow the orders of the guy with the experience.
I did notice that the guys that in RL were military or ex-military, tended to have E-4 to E-7 rank in the game. They tended to be more free lance about the "chain of command" but as a newly arrived draftee, who survived boot camp somehow, there was a definite pecking order.
Now if the Dumb Bunny, (read me or my character) came up with a suggestion that had merit, then the guys would at least listen.
Just my two cents!
