The battle group is usually commanded by a lieutenant-colonel selected on a rotational basis from one of the brigade units. The order of battle will vary depending on the task and the available manpower but generally includes an artillery battery with 105 mm C3 Close Support Guns, several companies of truck-mounted light infantry with support weapons, an armoured reconnaissance squadron with equipped with GPMGs/LAW, and a combat engineer troop. These combat arms troops will be supported by signals, service, medical and military police combat support sub-units. The brigades are commanded by a colonel and provide a garrison for the reserve units; however, they are usually ready to contribute a battle group to the Division's Task Force and battle school candidates to the Division's Training Centre. The June 30, 2016 / Project number: 16-0209 article published in the Canadian Army News stated that the Canadian Army trains 11,000 reservists annually on courses from private to lieutenant colonel. The number of courses increased in 2014/15 from the previous year and will see a steady state in 2015/16. The CA continues to generate and train ten Territorial Battalion Groups and four Arctic Company Response Groups each year.
