According to former Russia’s Main Intelligence Directorate (GRU) Colonel Stanislav Lunev, "SVR and GRU (Russia's political and military intelligence agencies, respectively) are operating against the U.S. in a much more active manner than they were during even the hottest days of the Cold War."[2] From the end of the 1980s, KGB and later SVR began to create "a second echelon" of "auxiliary agents in addition to our main weapons, illegals and special agents", according to former SVR officer Kouzminov.[3] These agents are legal immigrants, including scientists and other professionals. Another SVR officer who defected to Britain in 1996 described details about thousand Russian agents and intelligence officers, some of them "illegals" who live under deep cover abroad.
