This quick reference guide describes U.S. Army organizations, planning, and operations. Unified action partners (UAPs) are those military forces, of the private sector with whom U.S. Army forces plan, coordinate, synchronize, and integrate during the conduct of operations (Army Doctrine Reference Publication 3-0, Unified Land Operations).
Humanitarian assistance and disaster relief operations are not new to the Army and the Department of Defense (DOD). We gained experience from Hurricane Katrina in 2005 and the 2010 Haiti earthquake. In the response to the Ebola outbreak in West Africa, President Barack Obama announced Operation United Assistance in September 2014, allowing the military to support the United States Agency for International Development. This was the largest role the military had assumed in combating the spread of a disease or virus. The fight against Ebola was on.
