  Army Health System Command and Control
  The complexities of the competition continuum, the myriad of medical functions and
  assets, and the requirement to provide health care across unified land operations to
  diverse populations (U.S., joint, multinational, host nation, and civilian) necessitate a
  medical command authority that is regionally focused and capable of utilizing the
  scarce medical resources available to their full potential and capacity. Each of the
  medical command organizations (medical command [deployment support]
  [MEDCOM (DS)], medical brigade [support] [MEDBDE (SPT)], and medical
  battalion [multifunctional] [MMB]) is designed to provide scalable and tailorable
  command posts for early entry and expeditionary operations which could be expanded
  and augmented as the operational area matures and an Army and joint integrated health
  care infrastructure is established. The AHS command and control consists of both
  formal medical command organizations and the surgeon’s technical supervision at
  echelon of medical assets.
  SECTION I — OVERVIEW OF ARMY ECHELONS
  2-1. To ensure a seamless continuum of care from the POI or wounding to the CONUS-support base exists,
  and in order to decrease morbidity and mortality and to reduce disability, a synergistic effort is required
  between AHS table of organization and equipment (TOE) (operational forces) and table of distribution and
  allowances (the institutional force) organizations and resources and those found in other sectors of the
  CONUS-support base. The ability of the deployed medical commander to reach into the CONUS-support
  base for medical, technical, clinical, and materiel support is paramount to optimizing the medical outcomes
  of our Soldiers who become wounded, injured, or ill while on deployments. This reachback capability
  enhances the care given and maximizes the utilization and employment of scarce medical resources.
  OPERATIONAL ENVIRONMENT
  2-2. The future operational environment and our forces’ challenges to operate across the competition
  continuum represents the most significant readiness requirement. The logic chart (Figure 2-1 on page 2-2)
  depicted on the next page begins with an anticipated OE that includes considerations during LSCO against a
  peer threat. It depicts the Army's contribution to joint operations through the Army’s strategic roles. Within
  each phase of a joint operation, the Army's operational concept of unified land operations guides how Army
  forces conduct operations. In unified land operations, Army forces combine offensive, defensive, and
  stability tasks to seize, retain, and exploit the initiative in order to shape OEs, prevent conflict, conduct large-
  scale ground combat operations, and consolidate gains. Mission command guides commanders, staffs, and
  subordinates in their approach to command and control. The command and control warfighting function
  enables commanders and staffs of theater armies, corps, divisions, and brigade combat teams to synchronize
  and integrate combat power across multiple domains and the information environment. Throughout
  operations, Army forces maneuver to achieve and exploit positions of relative advantage across all domains
  to achieve objectives and accomplish missions.
  2-3. The logic chart (Figure 2-1 on page 2-2) depicts how the AHS supports the operating force. The AHS
  support logic chart is aligned with ADP 3-0, FM 3-0, ADP 3-37, ADP 4-0, FM 4-0, and JP 4-02.
