The Atlantic Base Commands (ABC) is a unit under the United States Army responsible for managing and operating military installations along the eastern seaboard of the United States, primarily supporting the Atlantic Fleet's vessels and aircraft. Established to facilitate logistical support for naval operations during World War II, these bases have evolved to cater to diverse needs in peacetime and wartime scenarios. They provide essential services such as housing, training facilities, medical care, and infrastructure maintenance for military personnel and their families. Key installations include Fort Bragg, Camp Lejeune, Naval Station Norfolk, among others. The Atlantic Base Commands play a crucial role in maintaining the readiness of U.S. forces within the Atlantic region and beyond.
