Since WW2, the Canadian Armed Forces have sent Gunners on at least 33 deployments around the world.

In 1956, Lester B. Pearson advanced Canada's international role in peacekeeping.  During the Suez Crisis, Canada sent troops to stabilize the region.  Pearson helped create the UN Emergency Force (UNEF).  Pearson won a Nobel Peace Prize for his efforts.

Over 33,000 Canadians completed six-month UNFICYP tours of Cyprus from 1964 to 1993.  Since 1974, over 12,000 Canadians have monitored the ceasefire in the Golan Heights.  From 1948 to 1988, Canadians represented 10% of UN peacekeepers or 80,000 personnel.

After the Cold War, the Canadian Forces focused on peacekeeping and peacemaking.  In 1993, Canada sent 1 RCHA to Yugoslavia with 81mm mortars.  They fired an illumination round to stop a firefight.

Since 1947, over 125,000 Canadians have served in UN missions.  A total of 130 Canadians lost their lives, including three Gunners.
