Numerous reports from Human Rights Watch and other sources have described the "hand-in-glove" manner in which the Government of Sudan and the nomadic ethnic militias known as the Janjaweed have operated together to combat a rebel insurgency in Darfur. Hundreds of eyewitnesses and victims of attacks have testified to the close coordination between government forces and their militia partners in the conflict. Militia leaders and members have been supplied with arms, communications equipment, salaries and uniforms by government officials and have participated in joint ground attacks on civilians with government troops, often with aerial bombing and reconnaissance support from government aircraft.
