The official honour guard of every branch is located in the National Capital Region, though nearly every military installation will have its own honour guard for local ceremonies and events. The honour guard units in National Capital Region, formed into the "Joint Service Honor Guard of the National Capital Region and the Department of Defense", an ad hoc unit of battalion size, represent the military as a whole and the United States as a nation, and perform numerous ceremonies on behalf of the President of the United States, the commander-in-chief of the federal Armed Forces, with musical accompaniment by each of the central bands of the Armed Forces based in the capital.
