On the evening of 7 June, the Norwegian Garnisonen i Sør-Varanger garrison heard the noise of powerful engines coming from the manoeuvres along the entire Soviet front of the Norwegian-Soviet border. Actual observations were not possible over the border in the dark. On that same night the GSV commanding officer ordered all GSV reserve forces to report to their emergency muster locations. The Soviet demonstration of strength lasted until 10 June, when the Soviet forces stood down. In 1979, Scott and Scott reported the headquarters address as Leningrad, L-13, Pod'ezdnoy Per., Dom 4.
