The Mission of the 7th Toronto Regiment RCA

7th Toronto Regiment, Royal Canadian Artillery has strength of just under 200 part-time soldiers organized into three batteries: 130 Battery, as a headquarters and training battery, 9 Battery, as a gun battery, and 15 Battery as a mortar battery. The day to day operations of the regiment are supported by a full-time cadre that consists of approximately ten officers and non-commissioned members who include several members posted in from the Regular Force (the full-time Army). As full-time staff, they prepare training exercises, conduct the unit’s routine administration and ensure that the unit’s plans and orders conform to the larger needs of the Canadian Army.

The weapon of the artillery is the “projectile”, usually taking the form of a high explosive (HE) 105 millimetre shell. These shells, using the C3 howitzers, are capable of engaging targets over 12 kilometres away, with a damage radius of 50 metres. 7th Toronto Regiment, Royal Canadian Artillery has four, C3 howitzers that are capable of firing HE, Smoke, Illumination, and High Explosive Squash Head (HESH) rounds to engage different forms of enemy and provide support to the infantry and armoured counterparts.
