> Petrov underwent intense questioning by his superiors about his judgment. Initially, he was praised for his decision.[2] Colonel-general Yuri Votintsev, the then-commander of the Soviet Air Defense's Missile Defense Units, who was the first to hear Petrov's report of the incident (and the first to reveal it to the public in the 1990s), states that Petrov's "correct actions" were "duly noted".[2] Petrov himself states he was initially praised by Votintsev and promised a reward,[2][22] but recalls that he was also reprimanded for improper filing of paperwork because he had not described the incident in the war diary.[22][23]

> Petrov has said that he was neither rewarded nor punished for his actions.[24] According to Petrov, he received no reward because the incident and other bugs found in the missile detection system embarrassed his superiors and the scientists who were responsible for it, so that if he had been officially rewarded, they would have had to be punished.[2][24][22][23] He was reassigned to a less sensitive post,[23] took early retirement (although he emphasized that he was not "forced out" of the army),[22] and suffered a nervous breakdown.[23]
