This publication is for skill level 1, 2, 3, and 4 soldiers holding military occupational specialty (MOS) 91x and for trainers and first-line supervisors. It contains standardized training objectives, in the form of task summaries, to train and evaluate soldiers on critical tasks that support unit missions during wartime. Trainers and first-line supervisors should ensure soldiers holding MOS/SL 91X1/2/3/4 have access to this publication. This manual applies to both Active and Reserve Component soldiers. This manual identifies the individual MOS training requirements for soldiers in MOS 91X. Commanders, trainers, and soldiers should use it to plan, conduct, and evaluate individual training in units. This manual is the primary MOS reference to support the self-development and training of every soldier. Use this manual with Soldier's Manuals of Common Tasks (STP 21-1-SMCT and STP 21-24- SMCT), Army Training and Evaluation Programs (ARTEPs), and FM 25-101, Battle Focused Training, to establish effective training plans and programs that integrate soldier, leader, and collective tasks.
