Really? The Russian army just disobeyed an order. Do you have a cite on that by any chance? Are any of them still alive?
It is the history of the fall of communism in the USSR. Demonstrators flooded the streets, the Army wouldn't fire on the people. Demonstrators put flowers in the tank barrels, and Boris Yeltsin climbed onto one of the tanks and gave his famous speech. A few days later, on August 24, 1991, Gorbachev dissolved the Central Committee of the CPSU, resigned as the party's general secretary, and dissolved all party units in the government. Good times.
