Active Service Force. The Calgary Highlanders mobilized on 1 September 1939 and joined the 2nd Canadian Infantry Division, moving to Shilo, Manitoba, in the summer of 1940 on the way to overseas employment. A 2nd Battalion was raised and served as a part-time Militia unit throughout the war. The Highlanders returned to Calgary on 24 November 1945 to a warm welcome, along with the 23rd Anti-Tank Battery (a component of the 2nd Anti-Tank Regiment) and the 91st Field Battery, Royal Canadian Artillery. The Calgary Regiment (Tank) mobilized in 1941 and eventually served in 1st Canadian Army Tank Brigade (later 1st Canadian Armoured Brigade), most famously serving at Dieppe but later being reconstituted and fighting in Sicily, Italy, and Northwest Europe. A reserve unit remained in Calgary. As well, a contingent of the Alberta University Canadian Officers Training Corps was located in the city.

Currie Barracks, and nearby Harvey Barracks, were both developed after the war to form Canadian Forces Base Calgary (CFB Calgary). A second armoury was built in a Northeast Calgary industrial park in the 1980s. Harvey Barracks (and the adjacent Sarcee Training Area) were returned to the Tsuu Tʼina Nation after the lease expired, and CFB Calgary was closed. Only the headquarters for a reserve brigade and a small area support unit remain. Current units Despite the closing of CFB Calgary (including both the Currie Barracks and Harvey Barracks), the city is
