How did Bullseye/Poindexter get into the FBI? (Or the army?)

In the Born Again show, Ben Poindexter is stated (in the prop documents) to only have a high school degree. However he achieved the rank of army 1st Lieutenant in "a couple of years". That would mean he went to officer school, right? Which you need a bachelors for? And then, on his FBI application, it states again that he has no college degree, which you also need to join the FBI. Is there a real life way that would happen or is this just an "it's a TV show" thing.
