During the events of the Soviet coup attempt in August 1991, Alpha Group's commanding officer, Gen. Karpukhin, was commanded by KGB chairman, Vladimir Kryuchkov, to forcibly enter the White House, Russia's acting parliament, after paratroopers secured the entrance, to eliminate the President of the Russian SFSR, Boris Yeltsin, and various other anti-coup leaders assembled there. In addition to Alpha Group, Gen. Karpukhin was also given authority of Vega Group (Vympel), elements of the Soviet Airborne, Internal Troops, special units of the Dzerzhinsky Division (OMSDON), mobilised units of the Moscow OMON, three tank companies, and a squadron of helicopters. On-site analysis of the area was conducted by Airborne deputy commander Alexander Lebed, and other senior officers who mingled with the crowds of anti-coup protesters nearest to the White House. There was a general consensus among the military officials who gathered that day, as evidenced by their statements months after the botched coup attempt, that had they followed through on their endeavour it would have succeeded. The stated mission objectives could have been reached in no more than half-an-hour, but it would have come at a terrible human cost. Shortly after their assessment was made, Gen. Karpukhin and Vympel's Boris Beskov convinced the KGB Deputy chairman, Gennady Ageyev, that such a massive undertaking should be cancelled.
