A Mustang is an officer who has earned a Good Conduct ribbon (or 4 years of enlisted service). Technically, STA-21 grads are Mustangs, but typically CWO/LDO's practice the rights and traditions that go along with the "cool tagname" <--gay. Anyway, show up at your first command, pat CWO5 on the back, call him a fellow Mustang, and see what happens. Better yet, wear one of those cool Mustang belt buckles too...
