The mission assisted the voluntary return of more than half a million refugees and internally displaced persons. It helped the government restore its authority and social services in areas previously controlled by rebels, recruited and trained about 4,000 police personnel with the help of a team of officers from Commonwealth countries, and constructed and renovated dozens of police stations. Meanwhile, the UK continued to assist the government restructure the army.
