Armed Forces Civilian Auxiliaries
Civilian wings of the U.S. military that play a support role to the main forces undertaking a variety of tasks which vary widely depending on the auxiliaries involved and the branch of the armed forces with which they are affiliated. Support missions may include air and sea search and rescue, harbor and coastal patrol, air/ground observation, radio communications and relay, aerial reconnaissance, air-to-ground photography, radiological monitoring, disaster and damage assessment, emergency response services, courier missions, aerospace education for members and the general public and cadet training.

Included are the Civil Air Patrol (affiliated with the U.S. Air Force), the U.S. Coast Guard Auxiliary, the Military Sealift Command (affiliated with the U.S. Navy), and the Sealift Command’s U.S. Naval Fleet Auxiliary Force.
Armed Forces Emergency Services
Programs operated by organizations such as the American Red Cross that help military personnel stay in touch with their families following the birth of a child, the death or serious illness of a family member or other family emergency.
Military Family Service/Support Centers
Programs located at military installations throughout the world that handle inquiries from military personnel, retirees, reservists and their family members, do an assessment of their needs and refer them to sources of help available at the installation or in the local community. The centers may provide relocation assistance, transition assistance, family life programs (e.g., parenting, stress management), individual and family counseling, employment assistance, and financial management services as well as emergency assistance.
The U.S. military includes five active duty service components and their respective Guard and Reserve units. All branches are equal parts of the United States Uniformed Services, headed by the President as Commander-in-Chief. The Army, Marine Corps, Navy, and Air Force fall under the jurisdiction of the Department of Defense (DoD). The Coast Guard reports to the Department of Homeland Security during peacetime and to the DoD (by way of the Navy) during wartime. Reserve and National Guard units perform as active-duty service members on a part-time basis. These troops train close to home, deploying when needed to aid in international conflict or domestic disaster relief.
