Royal Brunei Armed Forces

Brunei maintains three infantry battalions stationed around the country. The Brunei navy has several "Ijtihad"-class patrol boats purchased from a German manufacturer. The United Kingdom also maintains a base in Seria, the centre of the oil industry in Brunei. A Gurkha battalion consisting of 1,500 personnel is stationed there. United Kingdom military personnel are stationed there under a defence agreement signed between the two countries.

A Bell 212 operated by the air force crashed in Kuala Belait on 20 July 2012 with the loss of 12 of the 14 crew on board. The cause of the accident has yet to be ascertained. The crash is the worst aviation incident in the history of Brunei.

The Army is currently acquiring new equipment, including UAVs and S-70i Black Hawks.
