 197 soldiers of the UDR, including four women, were killed as active servicemen, with a further 61 killed after leaving the regiment, mostly by the Provisional Irish Republican Army.As a result of defence cuts it was eventually reduced to 7 battalions before being amalgamated with the Royal Irish Rangers in 1992 to form the "Home Service Battalions" of the Royal Irish Regiment.The history of militia in the United States dates from the colonial era, such as in the American Revolutionary War.
