4 Canadian Mechanized Brigade Group contained two mechanized battalions. These battalions each contained four mechanized infantry companies mounted in M113 armoured personnel carriers (APCs). In addition each battalion included a Lynx armed reconnaissance troop, a mortar platoon and an anti-tank defence platoon with 18 M150 TOW anti-tank vehicles.
The Improved TOW (Tube launched, Optically tracked, Wire-guided) missile weapon system is a soldier-portable and vehicle-mounted long range anti-armour weapons system. While it can be man-packed over short distances, the Canadian Defence Force usually mounts the TOW on a vehicle. In 4 Canadian Mechanized Brigade Group, the TOW missile systems were fitted to M113A2 Armoured Personnel Carriers. In this configuration it was known as a M150 TOW.
