An SFAB was projected to consist of 500 senior officers and NCOs, which, the Army says, could act as a cadre to reform a full BCT in a matter of months. In May 2017, the initial SFAB staffing of 529 soldiers was underway, including 360 officers. The officers will have had previous command experience. Commanders and leaders will have previously led BCTs at the same echelon. The remaining personnel, all senior NCOs, are to be recruited from across the Army. Promotable E-4s who volunteer for the SFAB are automatically promoted to Sergeant upon completion of the Military Advisor Training Academy. A team of twelve soldiers would include a medic, personnel for intelligence support, and air support, as cited by Keller.
