Army Techniques Publication ATP 4-44 / MCRP 3-17.7Q Water Support Operations October 2015 is the United States Army and United States Marine Corps manual for planning and executing water support for missions conducted across the full range of military operations. In the U.S. Army, water support operations are a Quartermaster Corps function, as well as a component of Army Logistics. Army Logistics is an element of the sustainment warfighting function, which provides the operational commander freedom of action, extended operational reach, and operational endurance. Water support operations include water treatment, storage and distribution. Water treatment is a field service function, while water storage and distribution are supply functions. In the U.S. Marine Corps, water support operations are a general engineering function, as well as a component of tactical-level logistics. Logistics is a warfighting function in the Marine Corps. Water support operations are critical to the U.S. Army and U.S. Marine Corps; they directly impact the depth and duration of military operations. ATP 4-44/MCRP 3-17.7Q will combine, restructure, and update information previously published in three field manuals: FM 10-52, Water Supply in Theaters of Operations, dated 11 July 1990. FM 10-52-1, Water Supply Point Equipment and Operations, dated 18 June 1991. FM 10-115, Quartermaster Water Units, dated 15 February 1989. ATP 4-44/MCRP 3-17.7Q contains numerous revisions. The title has been changed to Water Support Operations to correctly incorporate terminology from FM 4-40, Quartermaster Operations and JP 4-03, Joint Bulk Petroleum and Water Doctrine.
