Mustang (military officer): A mustang is slang term in the United States Armed Forces, referring to a warrant officer or commissioned officer who began his or her career as an enlisted service member.  "Mustang" officers are generally older and more experienced than their peers-in-grade who entered the military, without prior enlisted service, via commissioning from one of the service academies (such as the United States Merchant Marine Academy, United States Military Academy, United States Air Force Academy, United States Naval Academy, or United States Coast Guard Academy), Officer Candidate School, or the Reserve Officer Training Corps.  During the Vietnam War, however, when some Army warrant officer pilots were offered a direct commission to 2nd or 1st Lieutenant, they were usually younger than 25 at the time of commission.  Department of Defense military pay tables authorize approximately ten percent pay premiums for officers in grades O-1, O-2 and O-3 who have credit for over four years of enlisted or warrant officer service prior to commissioning (Grades O-1E, O-2E, O-3E).
