4 Canadian Mechanized Brigade Group (4CMBG;French:4^e Groupe-brigade mécanisé du Canada, 4GBMC) was a formation of theCanadian Army, thenMobile Command of the unifiedCanadian Forces. It was part of the European formation known asCanadian Forces Europe. The formation served as the main forward deployed land element of Canada's armed forces, and was stationed inWest Germany from 1957 until it was disbanded in 1993.^[1]

In 1951,27th Canadian Infantry Brigade arrived in Europe, to be succeeded by the1st Canadian Infantry Brigade in 1953, then 2 CIBG in 1955, then 4 CIBG in 1957.^[2] In 1959, when 4 CIBG's tour was due to end, a change was made in the reinforcement policy for Germany. Instead of whole brigades rotating every two years, the decision was made to keep 4 CIBG and its associated brigade units in place, instead rotating the major combat elements to Germany every three years.^[1]

The presence of the three mechanized infantry battalions led Canada's brigade in Germany to be renamed as 4 Canadian Mechanized Brigade Group on 1 May 1968, three months after Canada'sthree separate armed forces were unified into the singleCanadian Forces.

Around the same time, a review of Canada's foreign policy was announced by thePrime Minister,Pierre Trudeau, part of which involved an investigation into the role of 4 CMBG, which was the Canadian military's main overseas force. The ultimate result of the investigation was the announcement by the prime minister, as part of an overall cut in defence spending, to reduce the Canadian military commitment in Europe by half. 4 CMBG would also be re-roled – rather than its attachment as an active part ofBritish Army of the Rhine (BAOR), it would become a reserve attached to either theVII (US) Corps or II (German) Corps, relocating toLahr in Southern Germany.^[3] This downsizing and re-roling led to the withdrawal of the tactical nuclear weapons capability.

4 CMBG operated a large force ofCanadian tanks and armoured fighting vehicles and remained in place as one of NATO'sCold War tank formations. When the1st Canadian Division was reactivated in 1989, 4 CMBG became the forward deployed brigade of the division assigned to theCentral Army Group.^[4] When theGulf War began in 1990, the possible deployment of 4 CMBG to the Persian Gulf to serve alongside British Army forces in a Commonwealth Division similar to that from theKorean War was looked at and plans were drawn up to serve as the possible larger Canadian ground contribution in the Gulf (Operation Friction) under the name Operation Broadsword. However, logistical and political obstacles at home resulted in this plan being scrapped entirely and 4 CMBG remained in Germany.^{[1][5][6][7][8]}

The end of theCold War brought the final draw-down of Canada's military presence in Europe when the brigade was disbanded in 1993.^[1]
