 The various brigades and other formations and units number at least 100 @,@ 000 troops . The status of these brigades has been described as " pretty chaotic . " A 2007 disarmament and repatriation study said " army units that have not yet gone through the process of brassage are usually much smaller than what they ought to be . Some non @-@ integrated brigades have only 500 men ( and are thus nothing more than a small battalion ) whereas some battalions may not even have the size of a normal company ( over a 100 men ) . "
