(CAF) that provides combat service support to a brigade group and its elements. It is able to fight in a defensive role as well as provide the vital logistical support to sustain the operations of the other units within the brigade group. This is different to the "(service) battalion" designation in use in the British Army in 1914–1915 onwards. Such battalions were for war service only, having a temporary nature, like that of the concept of the French Army.


Sub-units

Service battalions are normally subdivided into: *A ''battalion headquarters'' (Bn HQ), concerned with overseeing the effective training and employment of all companies within the battalion. The HQ usually consists of the command staff, an orderly room, an operations cell, and a training cell. *A ''transportation company'' (Tn Coy), which provides transportation and movement support, both tactical and administrative, to the brigade. *A ''supply company'' (Sup Coy) which provides general supply support to the brigade. *A ''maintenance company'' (Maint Coy), which provides automotive, mechanical, electrical, weapon maintenance and support to the brigade. *An ''administration company'' (Admin Coy), which provides ''internal'' service support (signals and communication, transportation, supply, maintenance, food services, and military police support) to the battalion and its elements.


Flag

The unit flag of a service battalion is steeped with the traditions of its founding corps. The flag is a tri-color with the top and bottom equaling 2/5ths of the height each and the centre equaling 1/5th of the height. The official colours of the unit flag are Oriental blue (top) and marine corps scarlet (bottom) with an intervening gold stripe. Each battalion's flag has a large white Arabic numeral representing the number of the service battalion emblazoned on both sides in the flag's centre. These regal colours have a long history of association with army services. The Oriental blue colour of the flag is reminiscent of the

(5 CMBG), Valcartier, Quebec ** 5 Service Battalion (5 CMBG) Historically, 3 Service Battalion was located at CFB Gagetown, New Brunswick, in support of 3 CIBG until disbanded in the early 1970s. 3 Svc Bn served as the "experimental service battalion" from 1963, when brigade-level combat service support resources were pooled under a single commanding officer and headquarters. This model has served the Canadian Army, albeit with some changes, since being adopted by the other brigades in 1968. Based in the Federal Republic of Germany, 4 Service Battalion was created at CFB Soest in 1968 and moved to CFB Lahr in 1970 in support of 4 CMBG until the close out of Canada's NATO commitment there in 1993. Service battalions were historically part of Canadian mechanized brigade groups (CMBG), but were transferred to area support groups (ASG) in the late 1990s. In 2013, ASGs were renamed Canadian division support groups, and the service battalions were returned from these formations to the brigades. On 1 April 2010, the army reserve service battalions were modernized and aligned to represent the Canadian brigade group they were part of and to which they provide the combat service support (logistic and maintenance). Though the number of units was reduced from 19 to 10, the overall strength increased in-line with their role, the provision of combat support, logistic and maintenance resources to their respective Canadian brigade groups.

He deployed to Afghanistan with an establishment capped at 300 all-ranks that almost failed to fuel, fix and feed troops during Operation Medusa in the summer of 2006.
