The King ' s Own Calgary Regiment ( RCAC ) The King ' s Own Calgary Regiment ( RCAC ) , or KOCR , is an armoured unit of the Canadian Forces Primary Reserve based at the Mewata Armoury in Calgary , Alberta . The KOCR is part of 3rd Canadian Division ' s 41 Canadian Brigade Group . History . History 1910 – 1913 . The regiment originated in 1910 with the creation of the 103rd Regiment ( Calgary Rifles ) . History 1914 – 1938 . In 1936 , The Calgary Regiment was one of six infantry regiments designated to become a tank unit , being renamed Calgary Regiment ( Tank ) . History 1939 – 1945 . On 16 February 1941 the 14th Army Tank Battalion ( Calgary Regiment ) was mobilized at Mewata Barracks . When the Canadian Armoured Corps was created , the Calgary Regiment lost its status as an infantry regiment and transferred to the new corps . A reserve regiment remained in Calgary . The regiment was composed of 400 members of the reserve battalion , drawing also from reinforcement personnel from the Seaforth Highlanders of Canada and the Loyal Edmonton Regiment . The original ' A ' Squadron was drawn from Olds and district , ' B ' Squadron from Stettler area , ' C ' Squadron from Red Deer , and Headquarters from Calgary , High River , and Okotoks district . In March 1941 the regiment moved to Camp Borden , becoming part of the First Army Tank Brigade and in June 1941 sailed for Great Britain . Matilda tank s were initially used on the Salisbury Plains , but these were replaced later in the year by the first manufactured Churchill s . The overseas unit trained on various vehicles in Canada and the United Kingdom , and in August 1942 took the Churchill tank into battle for the first time at Dieppe . The unit was rebuilt after the raid , having left large numbers of tanks and crews behind . A notable casualty was Lieutenant Colonel " Johnny " Andrews , who was killed in action . In the spring of 1943 , Lieutenant - Colonel C . H . Neroutsos took command of the regiment . The new unit went to Sicily in 1943 with the 1st Canadian Army Tank Brigade , re - equipped with the Sherman tank . On 3 September 1943 the regiment assaulted the beaches of Reggio Calabria to little resistance and moved northwards with notable engagements in Potenza , Motta and Campobasso while supporting the 1st Canadian Infantry Division . On 21 November 1943 the regiment supported the 8th Indian Infantry Division in its assault against fierce German opposition on the Sangro River . In December the regiment met stubborn opposition fighting for the Moro River and later Vino Ridge and the Ortona Crossroads . On 11 – 12 May 1944 the regiment assaulted across the Gari River supporting the 19th Indian Brigade of the 8th Indian Division . During this operation and the advance towards the Hitler Line the regiment sustained casualties numbering 16 officers , 40 other ranks , and 60 tank casualties . An innovative use of a modified Sherman tank to carry a bridge across the Gari River is known as Kingsmill bridge by its inventor Captain T . Kingsmill ' s moniker . Kingsmill was to receive the Military Cross for the action . At this point Lieutenant - Colonel Neroutsos fell ill , and the regiment was taken over by Lieutenant - Colonel C . A . Richardson . In June 1944 the Calgaries took part in the Battle of Lake Trasimeno in support of the British 4th Division , after which the Calgaries conducted a pursuit up the Chiani Valley until the Lydia Line was reached south of Arezzo . By 3 August 1944 the regiment had advanced with the 8th Indian Division to the Arno River through country with remarkably poor tank going . On 25 August 1944 the Calgaries made an assault crossing of the Arno River , east of Florence pushing into the Sieve Valley where the Gothic Line was assaulted in the " Marradi " sector in support of the 1 / 5 Gurkha Regiment . Another miserably wet Italian winter was spent in the mountains . In late February 1945 the regiment was moved to Leghorn and embarked to Marseilles , France , where it moved by rail to the North - West Europe theatre . The regiment moved to the Reichswald Forest and on 12 April 1945 fought in the Second Battle of Arnhem , supporting the 49th ( West Riding ) Infantry Division to Ede , Holland . The regiment ' s final actions of the Second World War were in support of the 1st Belgium Brigade in clearing the resistance between the Never Thine and Waal Rivers . When the overseas unit returned to Canada in 1945 , it was disbanded , and the Calgary Regiment continued its service as a reserve armoured unit . History 1945 – 1999 . The cap badge was changed immediately after the war , as no badge is permitted to have any heraldic devices over the monarch ' s Crown . The sunburst , while part of the coat of arms of the City of Calgary on which the badge was based , was found to violate that principle . The addition of the " King ' s Own " designation was also made to the cap badge . The unit trained on Sherman tanks until 1968 , when the vehicles were finally retired . In the 1980s , the new AVGP Cougar was introduced into service , mounting a 76 mm main armament with co - axial C6 general purpose machine gun . These vehicles were used for training until the 21st century . In addition to an active Cougar squadron , an armoured reconnaissance squadron also trained on Jeeps and later the Iltis vehicle , usually mounting a C5 GPMG , or later the C6 GPMG .

The regiment turned in its Cougar AVGP vehicles in 2006 , thus suspending its training as an armoured regiment , and now fulfils the role of armoured reconnaissance . The primary vehicle at the unit is the Mercedes G - Wagen , known in the CF as the LUVW ( Light Utility Vehicle Wheeled ) . Soldiers also conduct dismounted reconnaissance tasks and domestic operations ( assistance during natural disasters such as floods , forest fires , and ice storms to name a few ) . Other soldiers conduct recruit training for new members of Calgary - based 41 Canadian Brigade Group units . In addition to many soldiers having served on United Nations tours in Bosnia , Croatia , Cyprus , Democratic Republic of Congo , Golan Heights and Darfur , members of the regiment have recently returned from operational tours in Afghanistan .
