  technologies and techniques that reduce and manage energy consumption. Improvisation techniques include
  efficient tactical power systems, micro-grids, battery management, rechargeable hybrid vehicle systems,
  environmentally generated energy, and power sources shared by multiple elements when and where feasible.
  CHEMICAL, BIOLOGICAL, RADIOLOGICAL, AND NUCLEAR
  7-44. Operations must account for possible enemy use of CBRN weapons. Sustainment units must be
  prepared to operate in, around, and through contaminated environments. This is fundamental to deterring
  adversaries from employing weapons of mass destruction. Sustainment units should incorporate CBRN into
  all facets of training as a condition on the battlefield that the enemy will leverage to establish and maintain a
  position of relative advantage. Commanders incorporate CBRN conditions into training to ensure mission-
  essential task proficiency in a contested CBRN environment.
  TRAINING SUSTAINMENT FORMATIONS
  7-45. Unit commanders at all levels are the critical link for implementing unit training management to ensure
  progressive readiness and unit proficiency within their formations. Sustainment commanders achieve unit
  readiness through progressive, rigorous, and repetitive training conducted in a challenging and uncertain
  training environment. A commander’s unit training plan must use a crawl-walk-run approach that
  progressively and systematically builds on successful task performance before progressing to more complex
  tasks. A progressive approach enables a logical succession, builds skills and knowledge from basic to advance
  tasks, and sets conditions for individual and collective training.
  7-46. With the majority of the sustainment force structure being in the Reserve Component, commanders
  must ensure these formations are well trained and integrated into the multi-component sustainment force
  structure prior to deployment. Commanders also leverage opportunities to strengthen sustainment training
  relationships with other Services, interagency organizations, private industry, and multinational partners
  whenever feasible.
  7-47. Commanders do not train sustainment units in isolation. Sustainment units do not operate
  independently, but as part of a larger force. Commanders must integrate and synchronize the employment of
  sustainment capabilities with the rest of the force to maximize combat power and achieve the overall
  objective of the operation. They develop organizational proficiency as part of a combined arms or joint team,
  supporting other warfighting functions to achieve specified outcomes by conducting multi-echelon training.
  Maneuver units and their supporting sustainment elements routinely train on resupply (including delivery of
  logistics packages), vehicle recovery, convoy operations, unit maintenance, casualty collection, HR support,
  and financial management team missions. Establishing FARPs and conducting refuel on the move operations
  to support extended moves for operations like attacks, mobile defenses, and defensive retrograde are other
  examples of key sustainment activities integrated into maneuver unit collective training events.
  7-48. Commanders maximize institutional and operational training opportunities at home station and ensure
  use of current tools such as HQDA-approved mission-essential task lists, proponent-approved combined arms
  training strategies, individual critical task lists, unit task lists, and associated training and evaluation outlines
  for collective tasks. The technical nature of sustainment core functions requires constant engagement and
  maintenance to prevent skill atrophy. Sustainment units strive for mastery-level proficiency of these essential
  tasks through multiple iterations of training events. That concept applies to not only the actual technical
  functions, but also to staff activities and basic field craft.
  7-49. Sustainment unit leaders plan, prepare, execute, and assess unit training in accordance with FM 7-0.
  Collective training events are conducted in accordance with combined arms training strategies. The combined
  arms training strategies are unit-specific training strategies that recommend a path for units to achieve and
  sustain training proficiency by identifying collective tasks to train and recommending training events to train
  those tasks using a crawl-walk-run approach.
  7-50. The Army’s standardized mission-essential task list defines the essential tasks a unit must perform to
  be considered proficient in its core mission. Soldiers leave the institutional domain with foundational
  individual competencies; unit commanders build on that technical foundation while also training the
  collective skills required by the unit’s mission-essential task list. Commanders use the mission-essential tasks
  and their associated training and evaluation outlines to assess unit collective training proficiency. These tasks
  have been developed and approved by the Army Training Development Capability and hosted on the Central
