BPST's mission is to coordinate UK military assistance to armed forces in Eastern Africa in order to contribute to Security Sector Reform and to increase peacekeeping capacity.  To fulfil this mission it has three main parts:

• The International Mine Action Training Centre (IMATC)
• Peace Support Training Centre (PSTC)
• A presence in the Kenyan Defence Staff College

BATUK is a small permanent administrative element based on the outskirts of Nairobi and provides the logistic support to visiting units.  Under an agreement with the Kenyan Government, three infantry battalions per year carry out six-week exercises in Kenya.

A Royal Engineer Squadron also deploys to Kenya over the same period to carry out a civil engineering project.

The training, named Exercise GRAND PRIX, takes place over the winter months and allows infantry battalions to carry out live firing, as well as experience a wide variety of climatic conditions, from desert to rain forest. They even learn some Swahili to aid relations with the local population.
