  4-60. FARPs may be easily detected by peer threat reconnaissance capabilities. Commanders must
  consider multiple FARP locations with short-term duration at any given site to remain survivable and
  operational. FARP site selection and mission duration depend on mission variables. Generally, FARPs in
  vulnerable locations should only be in place for 3 to 6 hours, and for as little time as possible with the
  smallest possible signature. Further, planners should consider the following when planning a FARP in close
  or deep areas:
  * Composition of the FARP should be austere.
  * Security is limited because the FARP is emplaced for a very short time.
  * A thorough map reconnaissance and intelligence update must be accomplished for the area.
  * Primary, alternate, and contingency FARP locations or teams should be considered to enable
  continuous operations.
  * One M978 heavy expanded mobility tactical truck fuel servicing truck typically contains enough
  fuel to refuel one AC/ACT or one AHC one time, depending on aircraft configuration.
  SECTION IV – HEALTH SERVICE SUPPORT
  4-61. The Department of Defense MEDEVAC system consists of an intra-theater MEDEVAC mission
  (typically performed by dedicated United States Army RW MEDEVAC units), and an inter-theater
  MEDEVAC mission (typically performed by designated United States Air Force FW assets). Together,
  they provide the vital linkage of assets required for a successful HSS system. The CAB supports the HSS
  function with medical personnel to provide casualty care, and with medical company air ambulance in the
  GSAB to provide MEDEVAC mission support.
  AVIATION MEDICINE
  4-62. Aviation medical support is directed by the brigade flight surgeon who coordinates with each of the
  aviation battalion’s medical personnel.
  4-63. The brigade flight surgeon, in conjunction with the physician assistant, operates the brigade aid
  station normally located in the brigade assembly area. The brigade flight surgeon advises and assists
  commanders on matters concerning the medical readiness of the command including preventive, curative,
  and restorative care. The brigade flight surgeon, with subordinate unit flight surgeons, conducts flight
  physicals for unit personnel. He or she also determines requirements for the requisition, procurement,
  storage, maintenance, distribution, management, and documentation of medical equipment and supplies for
  the unit.
  MEDICAL EVACUATION
  4-64. MEDEVAC of casualties is provided by the HHS system through the use of organic intra-theater air
  ambulance assets within the CAB. The aviation brigade has an organic air ambulance company assigned to
  the GSAB. Within the GSAB, the air ambulance company is organized to provide support from four
  separate operational locations. These operational locations are typically with the aviation task force, HSS
  organizations, a BCT, or higher echelons in order to provide the most appropriate AE support throughout
  the AO. Air ambulance aircraft are specifically equipped with critical care flight paramedic and equipment
  necessary for providing the required en route care of casualties. When AE assets are not readily available or
  the MEDEVAC requirement exceeds capabilities, the utility and cargo helicopters may be required to
  conduct aerial CASEVAC operations.
  4-65. The medical company air ambulance consists of 15 HH-60 aircraft, each with a capacity of 6
  patients. The HH-60 aircraft has maximum cabin space, carrying sophisticated, life-saving instruments and
  equipment for the medical attendants. HH-60s have the following unique capabilities that provide air
  ambulance MEDEVAC support for all categories of patients:
  * Rescue hoist with 600-pound capacity.
  * Multi-mission sensor thermal image sensor (HH-60M only).
  * Oxygen-generating systems.
