  * Fight to train.
  COMMANDERS ARE THE PRIMARY TRAINERS
  1-6. Commanders and leaders at echelon are responsible and accountable for the training and performance
  of their units. Commanders train and resource training one echelon down, and they evaluate to two echelons
  down. They are responsible for assessing unit training proficiency and prioritizing unit training. Subordinate
  unit leaders are the primary trainers of their elements. For example, a platoon leader is responsible for the
  training and performance of the platoon.
  NONCOMMISSIONED OFFICERS TRAIN INDIVIDUALS, CREWS, AND SMALL TEAMS; ADVISE
  COMMANDERS ON ALL ASPECTS OF TRAINING
  1-7. Noncommissioned officers set the foundation for Army training. They train Soldiers, crews, and small
  teams to be battle-ready. They provide crucial input and advice to the commander on what is trained and how
  it is trained. This ensures the organization trains on its most important tasks down to the individual Soldier.
  Noncommissioned officers—
  * Maintain responsibility for Soldier and small-unit training proficiency.
  * Identify and train Soldier, crew, and small-team tasks.
  * Help identify and prioritize unit collective tasks that support unit mission-essential tasks.
  * Train and enforce task standards.
  * Continually focus training on sustaining strengths and improving weaknesses.
  * Develop junior noncommissioned officers and help officers develop junior officers.
  * Provide timely and objective training advice to their officers.
  * Assist in planning, resource coordination, support, risk mitigation, supervision, and evaluation of
  training.
  TRAIN USING MULTIECHELON TECHNIQUES TO MAXIMIZE TIME AND RESOURCE
  EFFICIENCY
  1-8. The Army fights as a team, and whenever possible, trains at echelon as a team. Additionally, the
  simultaneous training of multiple echelons on complementary tasks is the most efficient and effective way
  to train because it optimizes the use of time and resources.
  TRAIN AS A COMBINED ARMS TEAM
  1-9. The Army fights as a combined arms team. To win, units must regularly train with the organizations
  they operate, and the capabilities with which they intend to fight. Leaders must proactively plan and
  coordinate training to account for as many elements and domains as possible with which they will operate.
  TRAIN TO STANDARD USING APPROPRIATE DOCTRINE
  1-10. The Army trains to standard using appropriate doctrinal publications. A standard is the proficiency
  required to accomplish a task under a specified set of conditions that reflect the dynamic complexities of
  operational environments to include cyber, electronic warfare, and hybrid threats. Units training to achieve
  task proficiency should use a regionally based, decisive action training environment (for example, Europe,
  the Pacific, Africa, or the Caucuses). Leaders continue to train high priority tasks even after units achieve
