# The Canadian Armed Forces — Army, Navy, and Air Force
The Canadian Armed Forces (CAF) defend Canada and contribute to international peace and security. Knowing the basic structure is part of the citizenship-test curriculum. Here is what you need to know.
The three branches
The CAF has three operational branches:
1. Canadian Army
The land forces. About 23,000 regular soldiers, plus reservists. Equipment includes tanks (Leopard 2), armoured vehicles, artillery, and infantry. Headquartered in Ottawa.
2. Royal Canadian Navy (RCN)
Canada's maritime forces. About 8,500 regular sailors, plus reservists. Operates frigates, submarines, patrol vessels, and Arctic patrol ships. Two main fleet bases: Halifax (Atlantic fleet) and Esquimalt, BC (Pacific fleet).
3. Royal Canadian Air Force (RCAF)
Canada's air forces. About 12,000 regular personnel, plus reservists. Operates fighter jets (CF-18 Hornets, transitioning to F-35), patrol aircraft, helicopters, transport planes (C-130, C-17), and search-and-rescue aircraft.
The three branches are unified under a single chain of command. Total strength: about 68,000 regular force + 27,000 reservists + 5,000 Canadian Rangers (a reserve component focused on the Arctic and remote regions).
Commander-in-Chief
The Commander-in-Chief of the Canadian Armed Forces is the King (currently Charles III). In practice, this role is exercised by the Governor General, who acts as Commander-in-Chief on behalf of the King. The Governor General signs commissions, presides at military ceremonies, and represents the Crown to the military.
The Prime Minister and Cabinet make actual policy decisions about military matters. The Minister of National Defence runs the day-to-day operations.
Allies and alliances
Canada belongs to several major defence alliances:
NATO
The North Atlantic Treaty Organization — a 31-member military alliance founded in 1949. Canada was a founding member. NATO's foundational principle is collective defence: an attack on one member is an attack on all.
NORAD
The North American Aerospace Defense Command — a unique binational US-Canada partnership for the air defence of North America. NORAD has been in continuous operation since 1958.
UN peacekeeping
Canada has a long history of UN peacekeeping. Lester B. Pearson, then-Foreign Minister, won the Nobel Peace Prize in 1957 for proposing the world's first major peacekeeping force during the Suez Crisis. Canadians have served on dozens of UN missions since.

World War II (1939–1945)
Over 1 million Canadians served. Canadian troops fought in the Battle of Britain, Dieppe Raid (1942), D-Day at Juno Beach (1944), the Battle of the Atlantic, and the liberation of the Netherlands.
Korean War (1950–1953)
Over 26,000 Canadians served under UN command. About 516 Canadians died.
Afghanistan (2001–2014)
Canada's largest combat deployment since WWII. About 40,000 Canadians served; 158 were killed.
Other operations
Bosnia, Rwanda, the Gulf War (1991), the war against ISIS in Iraq and Syria, NATO operations in Latvia (Operation REASSURANCE), and many UN peacekeeping missions.
Canadian Rangers
The Canadian Rangers are a unique reserve component — about 5,000 part-time soldiers, mostly Indigenous, who serve in remote northern, coastal, and isolated areas. They wear distinctive red sweatshirts and provide a Canadian Forces presence across the Arctic.
