The Army Reserve (previously known as the Territorial Force, Territorial Army (TA) and the Territorial and Army Volunteer Reserve (TAVR) from 1920 to 2014) is the active-duty volunteer reserve force and integrated element of the British Army. The Army Reserve was created as the Territorial Force in 1908 by the Secretary of State for War, Richard Haldane, when the Territorial and Reserve Forces Act 1907 combined the previously civilian-administered Volunteer Force, with the mounted Yeomanry (at the same time the Militia was renamed the Special Reserve). Most Volunteer infantry units had unique identities, but lost these in the reorganisation, becoming Territorial battalions of Regular Army infantry regiments. Some, notably the London, Monmouthshire and Hertfordshire Regiments maintained a separate identity.
