 The 3-inch mortar was the standard mortar used by Canadian infantry battalions during WWII. The weapons were grouped into a Mortar Platoon, first as part of Headquarters Company and from 1942 on as part of Support Company. Six such weapons comprised an infantry battalion commander's personal artillery.

 The weapon entered British service in the 1930s, and became widely issued in the Canadian Army in 1940, serving through to the end of the war, and eventually replaced by the US-designed 81mm Mortar.

 Historical references cite the calibre of the weapon as 76.2mm. The weapon has been noted for its weight and the long flight times for the ammunition to reach the target due to the high angle trajectory common to all mortars.
Transportation was usually done by Universal Carrier, on which 66 bombs could also be carried. The mortar was always dismounted to fire, and the advantage of a mortar was that it could be sited beneath ground level, behind a wall, or in otherwise "dead ground" and thus harder for the enemy to locate.

 The mortar could be broken down into a three-man load:

 Mortar No. 1 carrying the baseplate and optical sight (52 lbs)
 Mortar No. 2 carrying the barrel and spare parts bag (51 lbs)
 Mortar No. 3 carrying the bipod and one case of bombs (36 lbs)
