​TROOP (an adaptation of Fr. troupe, O. Fr. trope; cf. Ital. troppa, truppa; Med. Lat. truppus; the origin is doubtful; suggestions have been made that it represents a German conception of Latin turbo, crowd, or is an adaptation of Norw. torp, flock), a company or assemblage of persons, the term being usually applied in the plural to a body of soldiers of varying strength and of different arms. Specifically, a " troop " is one of the smaller units into which a regiment of horse-soldiers is divided, forming a subdivision of a squadron. Roughly speaking, it consists of sixteen files, and does not exceed from 30 to 40 sabres; in some armies, however, a maximum limit of 60 sabres are found (see Cavalry). For the military ceremony known as “ trooping of the colours, ” see Colours, Military.
