Chad's armed forces, l’Armee National du Tchad (ANT), is divided into its land forces and air forces. Its overall strength is approximately 25,000 soldiers. Much of the effective leadership is drawn from President Deby’s Zaghawa ethnic group. The Chad Government is pursuing plans to reduce the ANT’s personnel strength and professionalize the military.
Chad participates in the Trans-Sahel Counterterrorism Partnership, of which one element is a U.S. Government military-to-military assistance program that helps participant countries counter terrorist operations, border incursions, and trafficking of people, illicit materials, and other goods.
