The Canadians decided, as Soviet doctrine was to use waves of infantry and armoured vehicles to overcome opposition, that the .50 cal HMG could be used dismounted against both infantry and their lightly armoured personnel carriers as part of a defensive position. In the case of the Airborne Regiment, where they did not have armoured vehicles armed with similar weapons, a complement of tripod-mounted .50 cal heavy machine-guns was added to the weapons available to the airborne commandos. The Canadian Airborne Regiment also had a platoon of eight C3 81mm mortars.
