The Democratic Republic of Congo has been plagued by continued conflict and violence in the East despite the official ending of the war. And civilians have borne the brunt of this conflict. Security sector reform (SSR) is a critical element in ensuring security, stability and sustainable peace. This article examines security sector reform conducted by the UN Mission in Congo, and also refers to other actors involved in the process, focusing primarily on the East where insecurity is prevalent due to the non-integrated Congolese forces, the Armed Forces of the DRC, other armed groups and foreign, mainly Rwandan, troops. It contends that SSR is vital to protect civilians and that thus far MONUC has not fulfilled its mandate of protection.
