Regular Reserve (United Kingdom)

The Regular Reserve of the British Armed Forces largely consists of ex-Regular personnel who retain a statutory liability for service and are liable to be recalled for active military duty in a time of need. It also consists of a smaller number of ex-Regulars who serve under a fixed-term reserve contract (similar in nature to the Volunteer Reserve) and are liable for reporting, training and deploying on operations.

Since April 2013, Ministry of Defence publications no longer report the entire strength of the Regular Reserve, instead, only Regular Reserves serving under the fixed-term reserve contract are counted. As of 2014, they had a strength of 45,110 personnel. Of those, approximately 2,450 were serving alongside the Regular military in active service.

Royal Fleet Reserve
The Royal Fleet Reserve consists of ex-Regulars serving under a fixed-term reserve contract. As of 2014, they have a strength of 7,960 personnel.

Army Reserve (Regular)
The Army Reserve (Regular) of the British Army consists of Regular Reserves serving under a fixed-term reserve contract and are by far the largest of the armed forces Regular Reserves. As of 2014 they numbered 30,030 personnel and are divided into two categories. Category A is mandatory, with ex-Regulars automatically falling into this category upon leaving Regular service. Category D is voluntary, for ex-Regulars who are no longer required to serve in category A, but wish to continue, this normally lasts until the age of 55. Ex-Regulars in Both categories serve under the fixed-term reserve contract.

The Army Reserve (Regular) is distinct from and should not be confused with the British Army's Volunteer Reserve force of the same name, the Army Reserve.

Air Force Reserve
The Air Force Reserve consists of ex-Regulars serving under a fixed-term reserve contract. As of 2014, they have a strength of 7,120 personnel.
