  ARMY HEALTH SYSTEM SUPPORT DURING LARGE-SCALE
  COMBAT OPERATIONS
  5-121. Key AHS activities during large-scale combat operations include augmenting organic medical
  treatment and hospitalization capabilities for large-scale casualty producing events, providing medical
  support on an area basis, enabling prolonged care, clearing the battlefield of patients to facilitate movement
  and maneuver, and providing medical support to reconstitution operations. Army medical formations utilize
  the six AHS principles to provide medical support at the speed required by maneuver, within the constraints
  placed by sustainment, and in the best interest of the commander.
  5-122. The surgeon sections at each echelon conduct coordination, synchronization, integration, and planning
  of AHS support to large-scale combat operations within their echelon’s AO. At the national strategic level,
  the Office of the Surgeon General coordinates with the Defense Health Agency and the National Health
  System for increased requirements of medical services and the Armed Services Blood Program for blood and
  blood products, avoiding expiration through premature shipping and storage. The Surgeon General and
  FORSCOM surgeon work closely with HRC to develop medical force generation strategies in support of
  large-scale combat operations. Surgeon sections at EAB integrate, coordinate, synchronize, and plan area
  medical support, augmentation of organic medical capabilities and capacities, and medical support for large-
  scale casualty and evacuation events; enable prolonged care; and provide medical support to reconstitution
  operations. MEDBDE (SPT) commanders allocate AHS resources to support these tasks and provide AHS
  support to reconstitution operations as well as continued support to RSOI. See FM 4-02 for additional
  information on AHS support.
  TRANSPORTATION AND LOGISTICS CONSIDERATIONS FOR ROLE 3 MEDICAL TREATMENT
  FACILITIES
  5-123. The hospital center and subordinate detachments require a significant amount of logistics and
  transportation support getting to and once in theater. When planning for placement of Role 3 MTFs, medical
  planners should consider these requirements (as shown in Table 5-2), external support available, and the
  amount of time it will take to deconstruct, move, and construct a hospital. Planners and commanders cannot
  expect a hospital to relocate from one location to another and be able to provide the full complement of Role
  3 medical care in the new location in just two to three days. Executing the move of a hospital center may take
  a significant amount of time depending upon the distance required to move and training level of the unit. It
  is a significant undertaking that requires planning, coordinating for resources, evacuating all patients,
  systematically discontinuing services, disassembling and packing the facility, conducting the move, and then
  re-establishing the facility. Table 5-2 lists logistics and transportation planning factors for movement and
  sustainment of Role 3 MTFs.
