Vladimir Vasilievich Kvachkov (Russian: ?????´??? ????´?????? ??????´?; born 5 August 1948) is a Russian former Spetsnaz colonel and military intelligence officer, known for being arrested and charged for the attempted assassination of politician and businessman Anatoly Chubais in 2005, for which he was jailed for three years until he was acquitted on 5 June 2008.
Kvachkov did not admit nor did he deny his role in the assassination attempt, instead declaring the act not criminal, and that the elimination of Chubais and the present Russian government was justified as Russia is under the occupation of a "Judeo-Masonic mafia".
