  medical capabilities receive general support AHS support on an area basis, while organic medical elements
  at brigade and below provide direct support to parent units.
  SUPPORT TO ARMY SPECIAL OPERATIONS FORCES
  3-90. Though applicable across the range of military operations, ARSOF support planning and execution
  begins during competition below armed conflict. As discussed in Chapter 2, ARSOF sustainment structures
  (Ranger support companies, GSBs, and the 528th Sustainment Brigade [Special Operations] [Airborne]) are
  lean and unable to provide all sustainment functions required to support ARSOF missions. ARSOF
  sustainment structures are designed to perform the following tasks:
  • Enable expeditionary ARSOF missions.
  • Deploy early and rapidly.
  • Fill immediate and critical logistics requirements within organic formations.
  • Provide the capability to plug into theater logistics structures to achieve required endurance.
  • Tie the ARSOF units to the operational theater support structure.
  3-91. ARSOF rely on ASCC logistics structures to provide Service CUL to all Army forces in the operational
  area regardless of command structure. ARSOF routinely arrive in the operational area early, execute forcible-
  entry operations, and operate independently in small teams. Because of these factors, ASCC sustainment
  support to ARSOF is tailored to meet requirements based on the OE.
  3-92. For example, a special forces group-led combined joint special operations task force with its organic
  GSB cannot simply plug into the distribution network of a single DSB or sustainment brigade and execute
  tactical distribution to each of the special forces battalions, companies, and Operational Detachments Alpha.
  This is due to the GSB’s lack of organic capability and the fact that special forces groups do not deploy as a
  single entity. The GSB often supports a special forces group conducting activities across multiple locations.
  For this reason, CUL is required.
  3-93. In addition to CUL, ARSOF have requirements for SOF-peculiar equipment that requires supply,
  sustainment, and maintenance mechanisms outside of the Army common support structure. SOF-peculiar
  sustainment requirements are the responsibility of USASOC and United States Special Operations
  Command.
  SOF SUPPORT IN UNDEVELOPED THEATERS
  3-94. When a SOF unit deploys into an undeveloped theater during competition, it must bring sufficient
  resources to survive and operate until it establishes a bare-base support system or makes coordination for
  TSC or ESC, host-nation, or third-country support. All SOF units require services pertaining to food, water,
  and clothing, as well as medical and personnel needs. Operational project stocks and foreign-nation support
  agreements will be utilized as available. A bare-base support system may function from CONUS, afloat
  (amphibious shipping or mobile sea bases), or at a third-country support base. The bare-base support system
  relies heavily on strategic and tactical airlift or sealift for resupply.
  3-95. Deployed SOF units in an undeveloped AO may have to bypass normal logistics support echelons.
  These units may maintain direct contact with their parent units or may request a tailored support package
  from the 528th Sustainment Brigade (Special Operations) (Airborne) to accompany them into the theater of
  operations. The brigade can then request directly from the wholesale logistics system and provide support
  and sustainment to the ARSOF units. The brigade may also rely on theater OCS to obtain local support. The
  528th Sustainment Brigade (Special Operations) (Airborne) is capable of deploying a tailored brigade
  headquarters for command and control of operational-level logistics in support of ARSOF missions until
  relieved by ASCC logistics command and control capabilities. The brigade is capable of providing command
  and control of Army CSSBs operating in support of ARSOF for up to six months. In practice, the solution
  may be some combination of all options.
  SOF SUPPORT IN DEVELOPED THEATERS
  3-96. In a developed AOR, the ASCC establishes a sustainment structure that provides support to ARSOF.
  Pre-positioned war reserve materiel stocks, operational project stocks, and foreign-nation support agreements
  may provide support. The logistics force structure of ARSOF has the mechanisms to plug in to all joint and
