Eh, I met plenty of very smart people while serving. I also met plenty of very fucking stupid people. I’d say the ratio is about the same as the general population, since the military offers a lot of very attractive financial incentives to poor and middle class folks alike. Although, free college is the number one reason most enlist, in my experience. I know it was the main reason I did it. Gotta love a society that allows colleges to price gouge tuition so badly in the first place…
