Soviet Air Defence Forces officer (1939–2017)
Petrov
Stanislav Yevgrafovich Petrov was a Russian lieutenant colonel of the Soviet Air Defence Forces who played a key role in the 1983 Soviet nuclear false alarm incident.
On 26 September 1983, Petrov was the duty officer at the command center for the Oko nuclear early-warning system when the system reported that a missile had been launched from the United States, followed by up to four more. Petrov correctly judged the reports to be a false alarm.
