The Royal Ulster Rifles was an Infantry Battalion that would have had an MG Section as part of its Battalion Headquarters. These weapons would have been brigaded when the Machine Gun Corps was formed in 1915. The guns, and crews, would have been formed into a Machine Gun Company.
In 1922, the Machine Gun Corps was disbanded and the guns returned to the Infantry Battalion as a Machine Gun Platoon and then formed as a Machine Gun Company in the early 1930s.
This remained until the formation of Divisional Machine Gun Battalions in 1936 where guns were brigaded once again.
However during the Second World War, the 1st (Airborne) Battalion of the Royal Ulster Rifles became an Airlanding Battalion of the 6th Airlanding Brigade of the 6th Airborne Division. This Battalion therefore retained a Machine Gun Platoon within its support company. These guns were transport using 'Man Carry' and with Jeeps.
The 6th Airborne Division was formed on 3rd May 1943. It saw action at the following battles:
After the Second World War, the MG assets reverted to MG Platoons within support companies of Infantry Battalions.
