Strength

The strength of the Machine Gun Corps was recorded from January, 1915, until March, 1920, on a month-by-month basis.

At its peak, in December, 1918, it consisted of 9,707 officers and 149,089 other ranks – a total of 158,796 all ranks. A more detailed analysis is available on the MGC strength page.


Legacy

After it was disbanded in 1922, the veterans of the MGC were largely transferred to other units as machine gunners or infantry replacements.

The Machine Gun Corps Old Comrades’ Association was formed and published its first copy of the Emma Gee magazine in 1936.  A copy of the first draft of the magazine, marked up by Lt Col G S Hutchison is available to download.

There has never been a full history of the MGC written; however, the VMGCRA incorporates the MGC History Project that aims to complete this task.
