This is what we found on Wikipedia regarding the Newfoundland Regiment:

The Royal Newfoundland Regiment (R NFLD R) is a Primary Reserve infantry regiment of the Canadian Army. It is part of the 5th Canadian Division's 37 Canadian Brigade Group.

Predecessor units trace their origins to 1795, and since 1949 Royal Newfoundland Regiment has been a unit of the Canadian Army. During the First World War the battalion-sized Newfoundland Regiment was the only North American unit to fight in the Gallipoli campaign of 1915. Later in the war the regiment was virtually wiped out at Beaumont Hamel on 1 July 1916, the first day of the Battle of the Somme, but was rebuilt and continued to serve throughout France and Belgium until the armistice, then serving as part of the British Army of the Rhine in 1919. In December 1917, George V bestowed the regiment with the right to use the prefix "Royal" before its name. It was the only military unit to receive this honour during the First World War.

During the Second World War, the Newfoundland Militia was raised for defence and renamed the Newfoundland Regiment in 1943. The regiment remained in a home-defence role and also trained recruits for the two regiments of the Royal Artillery that were recruited in Newfoundland for overseas service. In 1949, Newfoundland joined Canada as the latter's 10th province and part of the Terms of Union required the re-creation of the Royal Newfoundland Regiment as the primary militia unit for the province. The regiment is ranked last in the Royal Canadian Infantry Corps' order of precedence.
