I was lucky to be accepted in the Marines - nearsighted all to beat heck and I had a broken back from a motorcycle crash - but they took me anyway. The Marine Corps tended to accept volunteers readily and thinned out the less motivated through the strainer of boot camp.
I am certain you would have been a fine soldier - the apple doesn't fall far from the tree. In a sense, I'm happy you didn't get into uniform. I saw way too many good, motivated young guys with excellent potential killed. We have that wall covered with their names.
I still like Heinlein’s formulation betsy: one MUST serve in order to vote, teach (certain subjects), or hold public office (of course the services must take you if that were the case). I’ve fried a few lib neurons when suggesting this as it actually WOULD make for a pool that would be more composed of non whites than anything else that could be done :-)
