Irregular tribal and former rebel militias and Popular Defence Forces supplement the army’s strength in the field. This is mixed force, having the additional duty of maintaining internal security. Some rebels currently fighting in the south are former army members.

Sudan’s military forces have historically been hampered by limited and outdated equipment. In the 1980s, the U.S. worked with the Sudanese Government to upgrade equipment with special emphasis on airlift capacity and logistics. All U.S. military assistance was terminated following the military coup of 1989.

During the 1990s, periodic purges of the professional officer corps by the ruling Islamist regime has eroded command authority as well as war-fighting capabilities. Indeed, the Sudanese Government admits it is now incapable of carrying out its war aims against the SPLA and NDA without employing former rebel and Arab militias to fight in support of regular troops. Oil revenues have allowed the government to purchase modern weapons systems, including Hind helicopter gun ships, MiG-23 fighters, Antonov medium transport aircraft, mobile artillery pieces, and light assault weapons. Sudan now receives most of its military equipment from the People's Republic of China, Russia, and Libya.
