After the main military offensive of the Second Chechen War ended and the separatists changed tactics to guerilla warfare, overall command of the federal forces in Chechnya was transferred from the military to the FSB in January 2001. While the army lacked technical means of tracking the guerrilla groups, the FSB suffered from insufficient human intelligence due to its inability to build networks of agents and informants. In the autumn of 2002, the separatists launched a massive campaign of terrorism against the Russian civilians, including the Dubrovka theatre attack. The inability of the federal forces to conduct efficient counter-terrorist operations led to the government to transfer the responsibility of "maintaining order" in Chechnya from the FSB to the Ministry of Internal Affairs (MVD) in July 2003.
