They use various equipment, including flags, rifles, and sabres, along with dance, to enhance the music of the marching band show . Usually, marching bands and color guards perform during football games at halftime . During marching band competitions, the guard adds to the overall score of the band and is also judged in a category usually called auxiliary . </P> <P> Color guards have since evolved into a separate activity known as winter guard, which is an indoor sport usually performed during the winter or spring, where the guard performs unaccompanied by the band, to a piece of pre-recorded music . Winter guards compete independently in such circuits as Winter Guard International (WGI) and Tournament Indoor Association (TIA), or Keystone Indoor Drill Association (KIDA). </P>
