The history of The King's Own Calgary Regiment (RCAC) began on 1 April 1910, when its predecessor the 103rd Regiment (Calgary Rifles), an infantry regiment of the Canadian non-permanent militia, was authorized and formed at Calgary, Alberta, Canada by General Order 38/10.[1]

With the outbreak of the First World War, the regiment was divided into several battalions for overseas service, which the King's Own perpetuate to this day. These battalions included the 50th, 89th and 137th, all of which saw service in Europe and were composed of men from central and southern Alberta.[3]

The 50th Battalion (Calgary), CEF, an infantry battalion of the Canadian Expeditionary Force, was authorized on 7 November 1914 and trained in Calgary and Sarcee Camp.[4]

The battalion arrived in France on 11 August 1916, where it fought as part of the 10th Canadian Infantry Brigade, 4th Canadian Division in France and Flanders until the end of the war. The battalion took part in the Battle of the Somme in October 1916, the Vimy Ridge in April 1917, and fought at Passchendaele.[4] During the Battle of Vimy Ridge, Pte. John George Pattison of the 50th Battalion CEF was awarded the Empire's highest award for gallantry, the Victoria Cross, for his heroic actions on April 10, 1917, storming a German machine-gun nest.[4]

During the conclusion of World War I, and the interwar years, the regiment changed roles and names several times, however, it has always maintained its ancestral home at Mewata Armoury in downtown Calgary. In 1924 the unit was titled "The Calgary Regiment". In 1936 it was one of a handful of infantry regiments selected to become an armoured unit. With this evolution, the name was changed to "The Calgary Regiment (Tank)".[3]

On 16 February 1941, the 14th Army Tank Battalion (Calgary Regiment) was mobilized at Mewata Barracks.[5] 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 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 tanks were initially used on the Salisbury Plains, but these were replaced later in the year by the first manufactured Churchills.

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. During the battle, the Battalion suffered casualties: two officers and eleven men were killed, 33 men and officers were wounded and taken prisoner with 143 other men; Only five of 181 men returned to England after the battle.[4] 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 First 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 Montecorvino 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, the Netherlands. The regiment's final actions of the Second World War were in support of the 1st Belgium Brigade in clearing the resistance between the Nederrijn 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.

Until 1968 the unit trained on Sherman tanks 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.

Members of the regiment continued the proud military tradition of the unit by volunteering for United Nations and NATO missions augmenting Canadian Armed Forces regular units on peacekeeping duties in Cyprus, Croatia, Bosnia, Congo, Golan Heights, and Darfur.

In 2006, the regiment turned in its Cougar AVGP vehicles suspending its training as an armoured regiment and taking on the role of armoured reconnaissance with the Mercedes G-Wagen, known in the Canadian Armed Forces (CAF) 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 Cyprus, Croatia, Bosnia, Congo, Golan Heights, and Darfur, members of the regiment volunteered on operational tours in Afghanistan.

Soldiers deploying on missions receive training on the full range of CAF vehicles including the Leopard C2, the TLAV, Coyote, the LAV III, and the Nyala (RG-31) armoured patrol vehicle.

Besides reconnaissance crewman and officers, soldiers of the regiment are also trained as mechanics, CIMIC operators, musicians (in the regimental brass and reed band), RMS clerks, and storesmen.

Canada's participation in the War in Afghanistan saw many soldiers from the regiment deploy in a variety of roles throughout the conflict. On September 24, 2007, the King's Own suffered its first combat fatality since the Second World War, when Cpl Nathan Hornburg was killed in action while serving in Kandahar province. Cpl Hornburg was posthumously awarded the "Mention in Dispatches" for his exemplary performance in combat. As a result of the unit's contribution to the War in Afghanistan, The King's Own were awarded the Afghanistan battle honour in 2014, which the regiment now proudly displays on their guidon.

In 2017, the regiment added a detachment into the High River, Alberta area, which currently parades at the High River Regional Airport. The regiment's aim is to eventually grow this detachment into squadron-sized unit. The regiment is also actively recruiting in the Okotoks, and Turner Valley regions.[6]

The regiment also assumed operational control of the 41 Canadian Brigade Group Influence Activities Company, composed of civil-military cooperation (CIMIC) and psychological operations (Psyops) trained personnel.

Since 2014, the unit has been increasingly training with civilian side-by-side all-terrain platforms, snowmobiles, and All-Terrain Vehicles, examining their utility during domestic operations and to supplement for rear echelon tasks.[7] On April 22, 2018 the regiment unveiled the Textron Tactical Armoured Patrol Vehicle (TAPV) during the unit anniversary St. George's Day.[8]
