This handbook sets forth the “how to fight” concept and commensurate training techniques at echelon that allow units to succeed at the National Training Center (NTC). Leaders at NTC specifically designed this handbook to help units at echelon understand an operational environment; develop tactics, techniques, and procedures for success; and better understand how to train for this environment at home station. By combining the lessons in this handbook with the Army’s current training strategies, units training at home station will arrive at the NTC better prepared to conduct large-scale combat operations against a near-peer threat.
