agreement, which is why the Tajik government was able to survive the war. The war was often thought to have been started by Islamic fundamentalists, but more accurately, it was a war between the regional clans and ethnic groups. By the mid-1990s, the National Army numbered to around 3,000. The majority of the officer corps were Russian, mostly veterans of the war in Afghanistan. The Ministry of Defense of Russia continued providing material support for the National Army. It was especially difficult for the Army to create its own military force due to the fact that many Tajiks preferred to serve in the Russian Army, due to the higher pay. Because of military opposition in the country, the regime had the largest military buildup in the Central Asian region. As of 1997, Tajikistan had two motorized rifle brigades (one of them is a training brigade), a special operations brigade and detachment (all primarily intended for the protection of the ruling regime), and a combined aviation squadron. Tajikistan further had a basic set of units and sub-units that provide operational, technical, and logistic support.

In 2007, the Air Force had 800 troops and 12 helicopters. The organizational structure of the Air Force is unknown. Tajik airspace is patrolled by the Russian Air Force. The Tajik Air Force remains small as Dushanbe doesn't expect an attack on Tajikistan from the air, and that Russian Air Force units at Gissar in Tajikistan and other such Russian contingents in Kazakhstan would detect any such assault. Tajikistan is also patrolled by Russian aircraft as part of the Joint CIS Air Defense System. The air force is mostly used for search and rescue missions, transportation, and the occasional attack on militant groups. For funding, the government relied upon modest foreign funds. In February 2013, a 20th anniversary parade occurred in Dushanbe, celebrating the creation of the armed forces. During the parade, 20 helicopters flew over the city. India made a deal in which the Tajik and Russian Air Forces share an air base. The base
