[2] The 172nd Battalion (Rocky Mountain Rangers), CEF, was authorized on 15 July 1916 and embarked for Great Britain on 25 October 1916.

[2] The regiment subsequently mobilized the 1st Battalion, The Rocky Mountain Rangers, CASF for active service on 1 January 1941.

It was redesignated as the 1st Canadian Infantry Training Battalion, Type A (Rocky Mountain Rangers), CASF on 1 November 1944.

[5] On 1 July 1898, five independent rifle companies were formed in the interior of British Columbia at Kamloops, Nelson, Kaslo, Rossland, and Revelstoke.

[6] With the advent of the First World War, the 102nd Regiment Rocky Mountain Rangers was placed on active service for local protection duties.

This task was taken over by the Royal Canadian Mounted Police by early 1940 as the regiment was down to almost nil strength due to reinforcement drafts to other active units.

In June 1940 the regiment, re-designated The Rocky Mountain Rangers CASF, was ordered to mobilise to full wartime strength.

During one notable deployment, the battalion marched from Kamloops to Vancouver as a training exercise under simulated war conditions.

To meet this threat the reserve unit, now re-designated the 2nd Battalion, was assigned to the 39 (Reserve) Brigade Group and tasked to provide protection of vulnerable industrial points along the CPR railway lines in the interior and to recruit and train as part of a brigade group in defence of the west coast.

With its headquarters remaining in Kamloops, the battalion was spread along the main and southern CPR rail lines from Ashcroft in the west to Fernie in the east.

As it was, the Japanese had abandoned the island several days before under the cover of fog and darkness, leaving a cannon which was later brought back to Vernon Military Camp.

The Rangers remained on the island until the middle of January 1944, losing an officer and several men to booby traps and friendly fire.

In 1983 Prince Philip, Duke of Edinburgh, presented the first official consecrated colours to the regiment in a ceremony at Kamloops.

The pandemic proved a challenging time for the regiment, and the Canadian Forces as a whole, as it had to make rapid changes concerning how it recruited and trained its members.

Although challenging, the leadership and members of the regiment were able to endure and accomplish its main priority in assisting to protect the people of Canada.

During the same period, the Rangers regularly deploy members onto Operation Lentus, the Canadian Armed Forces' response to domestic emergencies in British Columbia.

At its creation and throughout the First World War, the march was "St. Patrick's Day", a popular tune favoured by Lieutenant Colonel Vicars due to his Irish heritage.

As with other regiments, soldiers of the Rocky Mountain Rangers come to the position of attention when they hear the piper's tune and maintain this until the songs completion.

There are several Royal Canadian Army Cadets corps spread across British Columbia that are or have been affiliated to the Rocky Mountain Rangers.

Cadet units affiliated to the Rocky Mountain Rangers receive support and also are entitled to wear traditional regimental accoutrements on their uniforms.
