text: Introduction
  This field manual fully revises the previous Army’s physical readiness training (known as PRT) doctrine.
  The Holistic Health and Fitness (H2F) System directed by this doctrine is designed to address the readiness
  of every Soldier. Performance readiness experts of the H2F System will assess each Soldier’s physical and
  mental status and design programs to sustain or improve that Soldier’s ability to meet the demands of their
  military occupational specialties (MOSs), duty assignments, and combat-specific tasks. This individualized
  approach is sustained across the Soldier’s Army career. It represents a cultural shift from the industrial scale
  approaches of the past where massed formations received the same training in a one-size-fits-all approach—
  often with no equipment or expertise required to lead the training. It also represents a shift from expecting
  individual Soldiers who often train remote from their units to independently develop and implement a
  performance training program. The H2F System addresses those individual Soldiers’ needs, too. Figure
  introduction-1 illustrates the H2F System.
  Figure Introduction-1. The Holistic Health and Fitness System
  This doctrine directs leaders and Soldiers to use unit-level experts, facilities, and equipment to develop the
  physical and nonphysical components of Soldier readiness. This doctrine has evolved from the lessons
  learned, Soldier feedback, and Soldier testing throughout a prolonged period of ground combat. Lessons
  learned in that period are combined with the best performance and medical science to prepare Soldiers for a
  wide range of threats in complex operational environments. The H2F System is an immersive, comprehensive
  approach to readiness centered on brigade-owned H2F facilities and personnel.
  In the initial phase of H2F, recruits and new Soldiers will train to perform the Occupational Physical
  Assessment Test (OPAT) and prepare to conduct warrior tasks and battle drills (WTBD), high physical
  demand tasks (HPDTs), and the Army Combat Fitness Test (ACFT). In the sustaining phase of H2F, Soldiers
  will continue to build readiness. From their first units of assignment (FUAs) to separation from the Army,
  they optimize and mitigate the rate of loss of physical and mental preparedness for any mission at any time.
