"Only well armed and equipped, adequately trained and efficiently led forces can expect victory in future combat." General Matthew B. Ridgway
Individual
Crew
Team
Army training tradition and common sense have made the noncommissioned officer responsible for individual, and crew and team, training. Individual skill training is not presented to large numbers of soldiers by committee. Rather, the first line supervisor teaches individual tasks to soldiers in their organic squads, crews, or equivalent small units. The first line supervisor and his senior NCOs emphasize performance-oriented practice to ensure soldiers achieve soldier's manual standards. The first line supervisor conducts cross training to spread critical wartime skills within his unit. The CSMs, first sergeants, and other senior NCOs at every echelon coach junior NCOs to master a wide range of individual tasks. Commanders allot training time for NCOs to conduct individual training and require that individual tasks are included in all collective METL training. Noncommissioned officers are responsible for conducting individual 4-3 training to standard and must be able to explain how individual task training relates to collective mission essential tasks.
