<P> In modern times , the U.S. military plays ( or sounds ) `` Reveille '' in the morning , generally near sunrise , though its exact time varies from base to base . On U.S. Army posts and Air Force bases , `` Reveille '' is played by itself or followed by the bugle call `` To the Colors '' at which time the national flag is raised and all U.S. military personnel outdoors are required to come to attention and present a salute in uniform , either to the flag or in the direction of the music if the flag is not visible . While in formation , soldiers are brought to the position of parade rest while `` Reveille '' plays then called to attention and present arms as the national flag is raised . On board U.S. Navy , Marine Corps , and Coast Guard facilities , the flag is generally raised at 0800 ( 8 am ) while `` The Star Spangled Banner '' or the bugle call `` To the Colors '' is played . On some U.S. military bases , `` Reveille '' is accompanied by a cannon shot . </P>
