The Leicestershire Regiment consisted of Infantry Battalions 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.
During the Great War, the Battalions were distributed as follows:
At the commencement of the war, the 1st Battalion was part of the 16th Brigade, 6th Infantry Division.
On 17 November 1915, it transferred to the 71st Brigade, within the 6th Division. Its MG Section was transferred on 14 March 1916 to form the 71st Bde. MG Coy..
As a unit of the 6th Infantry Division, its MG Section will have taken part in the following battles and engagements.
| 1914 | |
| 19 and 20 September | BATTLE OF THE AISNE [I. Corps]. |
| 20 September | Actions on the Aisne Heights. |
| 13 October to 02 November | Battle of Armentieres [III. Corps]. |
| 1915 | |
| 09 August | Hooge [VI. Corps, Second Army]. |
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.
Upon the disbandment of Divisional Machine Gun Battalions in the post-WW2 restructure of the British Army, the Vickers Machine Gun assest reverted to individual Battalions as part of the Support Company as a Machine Gun Platoon.
