Master Sgt. Sarah Johnson (standing) with the 13th Battalion, 100th Regiment (13th, 100th) teaches a class in the 89B Senior Leader Course (SLC) on Jan. 28, 2020, in building 50 at Fort McCoy, Wis. In this course, instructors cover logistics and support operations as well as leadership skills. Soldiers attending the SLC are “seasoned” noncommissioned officers, meaning they’ve been in the career field quite a while and now get the opportunity to improve even more at their assigned skill sets. According to the Army job description for a senior ammunition supply specialist, these NCOs supervise the receipt, storage, issue, and preparation of ammunition, ammunition components and explosives for transportation and storage. They also supervise ammunition stock control and accounting procedures for surveillance inputs, conduct ammunition inspections and tests, and perform inspections of containers and vehicles transporting ammunition. The 13th, 100th, which falls administratively under Fort McCoy Regional Training Site-Maintenance, teaches the 89B10 Ammunition Supply Course, 89B Senior Leader Course, and the 89B Advanced Leader Course.
