  Phases
  The Army builds H2F training and testing across a Soldier’s career span in two phases:
  initial and sustaining. The training is based on an assessment of the needs of the Soldier
  and the unit. The testing validates that training has met the readiness needs of the
  Soldier and by extension his or her unit. This part of the doctrine discusses the two
  phases of the H2F System.
  INITIAL PHASE
  2-1. Initial phase training builds foundational and fundamental skill in Soldiering tasks: shoot, move
  communicate, survive and protect or treat. Within these tasks are physical and mental skills that Soldiers
  must acquire before the completion of IMT. Training prior to IMT is driven by the individual recruit in the
  FSP guided by information in this doctrine and the recruiter. Drill sergeants and their fellow cadre (who
  include H2F performance team members) conduct training in IMT in large, collective formations using H2F
  facilities and equipment.
  2-2. Initial phase training includes the FSP, BCT, advanced individual training (AIT), one station unit
  training (OSUT), Warrant Officer Candidate School (known as WOCS), Warrant Officer Basic Course
  (known as WOBC), basic officer leader courses, and the time spent acclimating to the FUA. Due to the
  varying lengths of these IMT programs, some Soldiers who finish sooner may stay in the initial phase after
  moving to their FUA until they are physiologically ready to move to sustaining phase activities. By the time
  Soldiers have completed six months of IMT, they are ready to move to the sustaining phase. H2F performance
  teams provide individual training and testing for those Soldiers who need more time to adapt.
  2-3. If a Soldier reaches the sustaining phase standards during AIT or OSUT, he or she can begin sustaining
  phase training. Progression to sustaining phase activity should not be an automatic expectation. Soldiers will
  arrive at their FUA medically ready, physically fit, disciplined, and lethal with their weapons. The variety of
  time spent in IMT means that some Soldiers’ physiological preparedness may not be at the same level as
  others. As discussed in Chapter 12, new Soldiers may have to modify training until they can safely join
  sustaining phase training.
  2-4. Initial phase training is much more prescriptive than sustaining phase training for these important
  reasons:
  * Untrained and deconditioned individuals must adhere to a training program that mitigates the
  relatively high risk of injury.
  * Initial phase Soldiers must learn the standard movements required for Soldiering.
  * Prescriptive, collective training is most feasible when there is a high trainee-to-cadre ratio.
  * Shared training experiences instill cohesion and improve the Soldierization process.
  FUTURE SOLDIER PROGRAM
  2-5. The FSP prepares individuals for the OPAT and the rigors of IMT. Detailed information for
  commanders in charge of preparing individuals and recruits for the physical demands of IMT is found in Part
  Four.
