  DEFENSE SECURITY COOPERATION AGENCY
  2-36. The Defense Security Cooperation Agency plays a critical role in competition. Its mission is to advance
  U.S. national security and foreign policy interests by building the capacity of foreign security forces to
  respond to shared challenges. The Defense Security Cooperation Agency leads the broader U.S. security
  cooperation enterprise in its efforts to train, educate, advise, and equip foreign partners. It administers security
  cooperation programs that support U.S. policy interests and objectives identified by the White House, DOD,
  and Department of State. These objectives include developing specific partner capabilities, building alliances
  and partnerships, and facilitating U.S. access. The Defense Security Cooperation Agency integrates security
  cooperation activities in support of a whole-of-government approach, provides execution guidance to DOD
  entities that implement security cooperation programs, exercises financial and program management for the
  foreign military sales system and many other security cooperation programs, and assists in the long-term
  development of the security cooperation workforces. It also provides guidance the United States Army
  Security Assistance Command on executing foreign military sales and security assistance requirements as
  requested by partner nations. Sustainers can leverage the Defense Security Cooperation Agency operation to
  facilitate partnerships and agreements.
  UNITED STATES ARMY MEDICAL RESEARCH AND
  DEVELOPMENT COMMAND
  2-37. The United States Army Medical Research and Development Command provides Army acquisition
  and technology support for medical materiel. This command manages and executes research in five basic
  areas—infectious disease, combat casualty care, military operational medicine, chemical biological defense,
  and clinical and rehabilitative medicine. The command works closely with the United States Army Medical
  Logistics Command to ensure the delivery of lifesaving medical products to the deployed force.
  UNITED STATES ARMY FORCES COMMAND
  2-38. Most Army conventional operating forces are designated as Service-retained forces in the Global Force
  Management Implementation Guidance assignment tables and are primarily based in CONUS. FORSCOM
  commands Active Component conventional forces (Regular Army, mobilized Army National Guard, and
  mobilized Army Reserve), executes training and readiness oversight of Army National Guard forces under
  state command, and does the same for non-mobilized Army Reserve units. FORSCOM is the command
  responsible for mobilization and demobilization. Based upon the landpower requirements developed by the
  CCMDs and validated by the Joint Staff, the Department of the Army and FORSCOM develop task-
  organized force packages to facilitate strategic deployment and support the gaining JFC's operational
  requirements.
  UNITED STATES SPECIAL OPERATIONS COMMAND
  2-39. USASOC is the ASCC of United States Special Operations Command and a force provider of ARSOF
  to the CCMDs. USASOC’s mission is to man, train, equip, educate, organize, sustain, and support forces to
  conduct special operations across the full range of military operations and spectrum of conflict in support of
  JFCs and interagency partners to meet theater and national objectives. USASOC major subordinate
  operational commands and units include 1st Special Forces Command (Airborne), special forces groups, 75th
  Ranger Regiment (Airborne), Army Special Operations Aviation Command (Airborne), 160th Special
  Operations Aviation Regiment (Airborne), 4th and 8th Psychological Operations Groups (Airborne), and
  95th Civil Affairs Brigade (Airborne).
  2-40. ARSOF sustainment organizations include the 528th Sustainment Brigade Special Operations
  Airborne, Special Forces group support battalions (GSBs), and Ranger support companies. Each special
  forces group has a support battalion, and each Ranger battalion has an organic support company. The
  remaining USASOC major subordinate operational commands possess minimal organic sustainment assets.
  ARSOF units rely on conventional Army organizations for sustainment support that exceeds the organic
