All officers have an undergrad degree, yes. A fair number have advanced degrees, but it’s not required for promotion. As with any other job, an advanced degree will help you to get noticed above the crowd, but it’s not a requirement. Right about now, the only requirement to make Lieutenant Colonel is that you have a pulse, not if you have a Master’s.

I'm a trifle behind the times, but I knew Army officers back in the day (Vietnam era) who didn't have undergraduate degrees. My husband was a "ROTC Jock" so of course he had his degree, and plenty of officers in his unit did also (the CO had an accountancy degree) but it wasn't universal.

I would think there must still be some OCS types who escaped unscathed by college . . . but I'm not really up to speed on what's going on now.
