In 1918, the Machine Gun Companies were organised under divisional command, rather than brigade, and MG Battalions were formed to co-ordinate them. They were then provided with their own chain of command and under the co-ordination of the Divisional Machine Gun Officer.

The MG Bns were disbanded with the re-organisations of 1922 and the disbandment of the Machine Gun Corps and the reversion to Machine Gun Platoons within Infantry Battalions.
