C3 81mm Mortar

The C3 81mm Mortar was a Battalion level indirect fire weapon which is capable of providing accurate High Explosive, smoke and illuminating rounds out to a maximum range of 5,650 metres.

Since the Second World War the mortar has been kept at the forefront of almost every nation's armoury and fresh designs have appeared in all major armies. The principal complaints of the war years - poor reliability and worse accuracy - have been overcome by better manufacturing techniques, though this has inevitably increased the cost. However, matters tend to balance out; whereas a wartime 3-in (76-mm) might have had to fire 100 bombs to get 30 into the target area and do worthwhile damage, today's (1978) 81-mm (3.2-in) mortar will put 30 bombs exactly where they are wanted, without waste.1

The 81mm mortar was introduced into the Canadian Army in 1967 and upgraded to C3 status commencing in 1968. Mortars were issued on a scale of eight per Regular Force Infantry Battalion.

Canada acquired 160 weapons, employing them in infantry battalions and mounting them on Armoured Personnel Carriers.

From the DND website:

The 81-mm mortar is an indirect fire support weapon used primarily by the infantry. A mortar crew can carry the weapon and some ammunition by backpack over short distances. A tactical advantage of the mortar is its high trajectory, which allows it to be sited behind high cover, to engage targets behind high cover, and to provide overhead support to friendly troops. The weapon can fire 20 rounds per minute for short periods and 15 rounds a minute for sustained periods. It can be used against targets between 200 and 4500 metres away. The mortar can fire high explosive rounds with a high degree of fragmentation in both ground and air bursts. It can also use red phosphorus rounds that produce a smoke screen and can also be used for signalling. Troops can also use illuminating rounds to light up the battlefield or for signalling.
