issued by President Boris Yeltsin on 16 July 1997. During 1998 altogether 580 units and formations were disbanded, 134 reorganised, and over 600 given a new jurisdiction. The redistribution of forces affected 95% of aircraft, 98% of helicopters, 93% of anti-aircraft missile complexes, 95% of the equipment of radiotechnical troops, 100% of anti-aircraft missiles and over 60% of aviation armament. More than 600,000 tons of material changed location and 3,500 aircraft changed airfields. Military Transport Aviation planes took more than 40,000 families to new residence areas. The short-lived operational commands were abolished. Two air armies, the 37th Air Army (long-range aviation) and the 61st Air Army (former Military Transport Aviation), were established directly under the Supreme Command. The former frontal aviation and anti-aircraft forces were organised as Air Force Armies and Anti-Aircraft Defense Armies under the military district commanders. There were initially four such armies with headquarters in St.Petersburg (Leningrad Military District), Rostov-on-Don (North Caucasus Military District), Khabarovsk (Far East Military District), and Chita (Siberian Military District). Two military districts had separate Air and Air Defence Corps. When the Transbaikal Military District and Siberian Military District were merged, the 14th Air and Air Defence Forces Army was formed to serve as the air force formation in the area. The number of servicemen in the air force was reduced to about 185,000 from the former combined number of 318,000. 123,500 positions were abolished, including almost 1,000 colonel positions. The resignation of 3000 other servicemen included 46 generals of which 15 were colonel generals. On 29 December 1998 Colonel General Anatoly Kornukov, a former Air Defence Forces officer and new commander-in-chief of the merged force, succeeding Deynekin, reported to the Russian defence minister that the task had 'in principle been achieved'. General Kornukov established the new headquarters of the force in Zarya, near Balashikha, 20 km east of the centre of Moscow, in the former PVO central command post, where the CIS common air defence system is directed from. 2001–2010 In 1999 Vladimir Putin became Prime Minister of Russia and then President in 2000; he continued to hold one or the other of these offices through every year since. In December 2003 the aviation assets of the Russian Ground Forces—mostly helicopters—were transferred to the VVS, following the shooting down of a Mi-26 helicopter in Chechnya on 19 August 2002 that claimed 19 lives. The former Army Aviation was in its previous form
