Oh, being spit upon while in uniform, back in the 60s and 70s might have something to do with it.
My brother-in-law made lieutenant colonel out of Army ROTC at Iowa State as the honor graduate. That’s not bad. But if you’re an academy graduate and you only get to O-5, you might want to reevaluate your trek upwards. OTOH I knew several land grant college general officers.
Just my Spec/6 two cents.
