A brigade was a military unit within the Kaleesh military organization referred to as the Kolkpravis. Commanded by a Baatar, a brigade was composed of one to two hundred Hordes, each under the leadership of a Tarkhan and containing one hundred kamen led by a blackarm. Because brigades were frequently dispersed across a large area during combat operations, the baatar in charge had to depend on couriers to maintain contact with the various hordes. The khanate, the largest military formation under the kolkpravis, was made up of multiple brigades and was under the direction of one of the eight Khans of the Izvoshra.
