I have considered it, but not seriously.
I’m already too old for the Marines, Air Force or Coast Guard, and I don’t really think I’m a military sort of guy.
My concentration in law school (government procurement/contracts) is something that would give me a leg up in that direction, but I think I prefer to remain a civilian.
Also, I enjoy inhaling the results of the combustion of plant matter, and as I understand it, the military frowns on that.
