Although there was an ad hoc regiment with this number, raised during World War 1 with troops drawn from the various existing Gurkha units, the troops mostly retained the uniform and insignias of their respective regiments (with a few exceptions who wore 11 GR badges which was unofficial as no sanction was given for such). This regiment was disbanded in 1922 and has no relation to the present-day 11 Gurkha Rifles, despite claims to the contrary.
