The Romanian armed forces have been reorganized in the wake of the revolution of 1989–90, which destroyed the Communist armed forces and security establishment. In 2002, the armed forces numbered 99,200 active personnel, supported by 130,000 reserves. There were 66,000 in the army, 6,200 in the navy, and 17,000 in the air force, which had 202 combat aircraft and 21 attack helicopters. The paramilitary of 79,900 consisted of armed border guards and a gendarmerie. Romania participated in Operation Enduring Freedom in Afghanistan, and in peacekeeping missions in six other regions. Defense expenditures in 2002 were $985 million, or 2.5% of GDP.
