Chad's armed forces numbered about 36,000 at the end of the Habre regime but swelled to an estimated 50,000 in the early days of Idriss Deby. With French support, a reorganization of the armed forces was initiated early in 1991 with the goal of reducing the size of the armed forces. An essential element of this effort was to make the ethnic composition of the armed forces reflective of the country as a whole. While the militaryís size has been reduced to approximately 25,000 soldiers, leadership positions are still dominated by the Zaghawa.

War and rebellions have tapered off in recent years. Following Idriss Deby's rise to power, Habre loyalists continued to fight government troops and rob civilians around Lake Chad. In the mid- and late-1990s, a rebellion in the south by the FARF delayed the promised oil development until crushed by government forces. Most recently, The Movement for Democracy and Justice in Tchad (MDJT) launched the most serious threat to Deby's hold on power, but little progress was ever made on either side. In January 2002, the government and the MDJT signed a formal peace accord. Although remnants are still present in the North, active rebellion has been negligible since late 2003.

Long, porous borders continue to render Chad vulnerable to incursions. In March 2004, the Algerian terrorist organization, the Salafist Group for Preaching and Combat (GSPC), strayed into Chadian territory, where they were engaged by Chadian armed forces. Since the outbreak of the Darfur crisis in Sudan, armed militias have occasionally crossed into Chad, resulting in small-scale skirmishes. In response to such ongoing threats Chad has joined in the Pan Sahel Initiative (PSI), a USG military-to-military assistance program which helps participant countries counter terrorist operations, border incursions, and trafficking of people, illicit materials, and other goods. Initial PSI training was completed in Chad in July 2004.
