Vympel (the Pennant) – formerly known as an elite cold war -era KGB sabotage and assassination unit – is now also a counter-terrorist and counter-sabotage unit. But, unlike "Alfa", instead of learning how to storm airplanes and buses, they operate in an entirely different environment. They are experts in 18 special disciplines (among which - how to infiltrate guarded buildings, extensive marksmanship and martial arts training, driving APCs and flying airplanes, and medical training) and are Russia's last defense against possible terrorist acts involving nuclear plants,hydroelecrtric dams, and other industrial complexes. However, "Vympel" operatives are still heavily used in special operations missions in the Northern Caucasus, along with their counterparts from "Alfa" unit. "Vympel" has 4 operative units, "Alfa" has 5 operative units. One unit from each Department is always participating in offensive operations in Chechnya.They constantly rotate their troops, and each operative unit is stationed in Chechnya at least 2-3 times per year. Vympel is stationed in Moscow, but it also has multiple branch offices in virtually every city where there is a nuclear power plant.(from wikipedia)
