The Sudan People’s Armed Forces is the regular forces of Sudan and is divided into five branches; the Sudanese Army, Sudanese Navy (including the Marine Corps), Sudanese Air Force, Border Patrol and the Internal Affairs Defense Force, totalling about 200,000 troops. The military of Sudan has become a well-equipped fighting force, thanks to increasing local production of heavy and advanced arms. These forces are under the command of the National Assembly and its strategic principles include defending Sudan’s external borders and preserve internal security.
However, since the Darfur crisis in 2004, safe-keeping the central government from the armed resistance and rebellion of paramilitary rebel groups such as the Sudan People’s Liberation Army(SPLA), the Sudanese Liberation Army (SLA) and the Justice and Equality Movement (JEM) have been important priorities. While not official, the Sudanese military also uses nomad militias, the most prominent being the Janjaweed, in executing a counter-insurgency war. Somewhere between 200,000 and 400,000 people have died in the violent struggles.
