  obtain medical and/or dental treatment. Functions include medical regulating, patient evacuation, and en
  route medical care. (ATP 4-02.2). For more information on aeromedical evacuation, refer to DODD
  5100.01, JP 4-02, and ATP 4-02.2.
  PATIENT EVACUATION
  1-21. In today’s OE, the reduced medical footprint forward places a high demand on en route care
  capabilities. Consequently, patient evacuation capabilities are even more critical than in the past and the
  United States Army in coordination with the other Service medical elements must integrate with lift
  operations, as well as with the associated capabilities of multinational forces.
  SECTION IV — ARMY HEALTH SYSTEM PRINCIPLES
  1-22. The principles of the AHS are the foundation (enduring fundamentals) upon which the delivery of
  health care in a field environment is founded. The principles guide medical planners in developing operation
  plans (OPLANs) which are effective, efficient, flexible, and executable. Army Health System support plans
  are designed to support the operational commander’s scheme of maneuver while still retaining a focus on the
  delivery of health care.
  1-23. The AHS principles apply across all medical functions and are synchronized through medical
  command and control and close coordination and synchronization of all deployed medical assets through
  medical technical channels. Figure 1-3 depicts the AHS principles.

  CONFORMITY
  1-24. Conformity with the operation order (OPORD) is the most basic element for effectively providing
  AHS support. In order to develop a comprehensive concept of operations, the medical commander must have
  direct access to the operational commander. Army Health System planners must be involved early in the
  planning process to ensure that we continue to provide AHS support in support of the Army’s strategic roles
  of shape OEs, prevent conflict, prevail in large-scale ground combat, consolidate gains and once the plan is
  established it must be rehearsed with the forces it supports. In operations with a preponderance of stability
  tasks, it is essential that AHS support operations are in consonance with the combatant commander’s (CCDR)
  area of responsibility (AOR) engagement strategy and have been thoroughly coordinated with the supporting
  assistant chief of staff, civil affairs (CA) operations (G-9).
