The Scout troop is a unit of Scouts, Boy Scouts, Girl Guides and Girl Scouts that usually meet weekly. Girl Guides often use Unit or Company instead. The troop is the fundamental unit, which a Scout joins and via which he or she participates in Scouting activities, such as camping, backpacking, and canoeing. The troop leadership, youth and adult, organizes and provides support for these activities. The troop size can vary from as few as a half-dozen Scouts to several dozen. Troops work on badges and awards together, and arrange activities, events, and camping trips together.
