U.S. Army All-American Marching Band

The U.S. Army All-American Marching Band was a U.S. Army-sponsored civilian marching band competitively recruited from high school senior musicians early each December and dissolved the following month. First organized in 2007 and discontinued in 2019, it was neither an active, nor reserve component band and its performances were limited to events during and preceding the U.S. Army All-American Bowl in San Antonio, Texas, including the halftime show of that event.
