expanded. It handled the recruiting, training, supply, medical care, transportation and pay of two million soldiers, comprising both the regular army and the much larger temporary volunteer army. The war department established a sea-going transport service of its own, independent of the
Navy Department. ATS was maintained as a branch of the
Quartermasters' Department. A fleet of steamboats and pilot-boats were used in the military campaigns in the Eastern Carolinas. This was the origin of the United States Army Transport Service. Many battles were won because of the Army Admiral's ability to swiftly and effectively move troops and supplies.

During peacetime ATS was to operate directly under the Quartermaster General through a General superintendent at home ports and in wartime, when formal ports of embarkation were to be established, ATS would come under the port commander's jurisdiction. During the interwar period, ATS Atlantic was based at the New York General Depot, Army Supply Base, in Brooklyn and ATS Pacific and the transport docks were at the San Francisco General Depot, Fort Mason, California. The Army considered maintenance of a nucleus of military personnel, intimately familiar with both military requirements, port and ship operations, that could form the core of a full
port of embarkation staff in wartime or other emergency as one of the reasons for maintaining ATS itself. Coordination with other Army transport functions was aided by the fact ATS was one of the four interwar divisions of the Army Transportation Service which also had divisions responsible for rail, motor and animal transport.
ATS itself became absorbed into the Water Division of the United States

The vessels themselves were commanded by civilian merchant mariners with a civilian crew. The large troop transports had military representatives or the Quartermaster or Transportation Corps aboard that were designated as transport commanders, on larger vessels with extended staff, with authority over all embarked personnel but no authority over the ship itself. On smaller vessels or cargo ships a single officer would represent the Corps. The ships were not armed except during wartime when naval type guns were installed.
