My recollection is that the 18 series was introduced to the enlisted side first, although it must have been in '84, as it didn't happen when I was a detachment commander in '83. September is when I got designated as an 18A...officers didn't have an S suffix, but rather 5G, so as an infantry officer I was an 11B005G. Actually, my duty MOS as a lieutenant was 48E005G, Unconventional Warfare Officer. As they were developing the 18 Specialty Code, that changed. The Foreign Area Officer types didn't like being saddled with SF types.
