 CONT: Mac refers to himself as a Lieutenant at the time of the 1983  Beruit Marine Corps Barraks bombing and there is a photo of a Marine  Corps ID showing Macs rank as "LT" (an officer), but another  document shows him separating from the Marine Corps in 1992 with the  grade of "Sgt" (an enlisted rank), which would have been a demotion  and not at all in line with Macs character.
