I think you can take "orders"......
Anyway, I'm not sure there is a "military-type" personality, in order to serve. My 'bro went through officer training corps, and boot camp. And he served basically as a desk jockey. And he was a straight A student, and played chess in high school. Totally cerebral.
I'm curious as to why IHG wouldn't want me in a foxhole. I'm trustworthy. I wouldn't try to trade him to the enemy to save myself. Most likely.
