Winterguard is an indoor colourguard activity, derived from the outdoor summer activity that is commonly part of a Marching Band or Drum Corps. Winterguard is usually performed in an indoor arena. Guards perform to a recording of various musical genres. A winterguard unit performs using dance, and most of all, with various pieces of equipment. While equipment can vary from anything to everything, flags, rifles, and sabres are the main pieces of equipment. Members toss, spin, and do much more with their equipment, which can change throughout their show.
Major competitions take place from January to March with Finals taking place in April. Competitions are sanctioned and managed by Winter Guard United Kingdom (WGUK).
