Question to the Ministry of Defence:

To ask the Secretary of State for Defence, how many UK service personnel have been stationed at the British Army Training Unit Kenya in a (a) permanent and (b) temporary capacity in each of the last 10 financial years.

As at October 2025 (latest available figure) there were 200 UK Regular¹ Armed Forces Service personnel permanently stationed² at the British Army Training Unit Kenya (BATUK³).

Notes/Caveats

1. UK Regulars comprise full time service personnel, including Nursing Services, but excluding Full Time Reserve Service (FTRS) personnel, Gurkhas, Mobilised Reservists, Military Provost Guard Service (MPGS), Locally Engaged Personnel (LEP), Non Regular Permanent Staff (NRPS), High Readiness Reserve (HRR) and Expeditionary Forces Institute (EFI) personnel. Includes trained and untrained personnel.
2. The figures are based on Service personnel's stationed location and not their location of residence - where personnel work isn't necessarily where they live. Personnel deployed on operations to an area away from their stationed location are shown against their most recent stationed location. The Royal Navy/Royal Marines personnel on sea service are included against the local authority containing the home port of their ship.
3. BATUK has been derived from the Location Unit field in Joint Personnel Administration (JPA).
4. Figures have been rounded to the nearest 10 to prevent inadvertent disclosure. However, numbers ending in "5" have been rounded to the nearest 20 to prevent systematic bias.

Notes/Caveats

1. Deployment data are derived from the Joint Personnel Administration (JPA) `Move and Track` system. Due to ongoing validation of data from JPA, figures provided are provisional and subject to change. Figures have been derived from the October 2025 deployment extract.

3. ‘UK Forces Service Personnel’ comprises UK Regular Forces, Gurkhas, Military Provost Guard Service (MPGS), Locally Engaged Personnel (LEP), Volunteer Reserve, Serving Regular Reserve, Sponsored Reserve, and Full Time Reserve Service (FTRS).
4. Service personnel data is derived from the JPA system, which is a combination of mandatory and non-mandatory fields populated by unit administrators and voluntary fields that Armed Forces personnel can choose to complete based on their perceptions.
5. The Date of Deployment is the 'deployed date in' as recorded on JPA 'Move and Track' system. This is the date personnel deployed into the respective count.
6. Please note: the total does not include repeat tours within the same calendar year so each individual is only recorded once per financial year. If personnel began a deployment in multiple financial years, then they would be reported in each financial year they were deployed in. Hence, figures can not be combined to give an overall number of unique personnel deployed over this whole period.

8. The Financial Year for Defence Statistics purposes starts on 1 April and ends on 31 March.
