The Carl Gustaf M2 recoilless rifles are mainly used by Reservists, while the M3 rifles, with lighter weight and strengthened structure, are used by the Regular units. Three types of portable anti-tank weapons are currently in service with the Army: The Carl Gustaf recoilless rifle, M72 LAW rocket propelled grenade (RPG) launcher, and the BGM-71 TOW wire guided missile. Hence, sufficient capabilities in this regard are required for all infantry units of the Army. It would be detrimental for an infantry unit to face enemy main battle tanks (MBT) without the right weapons. However, due to a change in NATO doctrine emphasizing air- and armour-based anti-tank capabilities and federal budgetary issues, training and procurement of infantry-based anti-tank capabilities have fallen behind, especially for Reservists. The Canadian Army is no stranger to these weapons, as they have long been used.

The large variety of such weapons can be divided into two categories: Rockets and missiles.

Recent combat experiences in Ukraine have shown that portable anti-tank weaponry gives infantry a chance to fight against armoured targets, which are immune to rifles and grenades.
