Operation Motorman was a large operation carried out by the British Army in Northern Ireland during the Troubles. The operation took place in the early hours of 31 July 1972 with the aim of retaking the "no-go areas" that had been established in Belfast and other urban centres. In Derry, Operation Carcan, initially proposed as a separate operation, was executed as part of Motorman.

HQ Northern Ireland was the formation responsible for the British Army in and around Northern Ireland. It was established in 1922 and disbanded, replaced by a brigade-level Army Reserve formation, 38 (Irish) Brigade, in 2009.
