Vostok 2018 was a large-scale Russian military exercise, held from 11 to 17 September 2018, throughout Siberia and the country’s Far East. The exercise involved units from the Army, Air Force and Navy. China, Mongolia, as well as NATO member Turkey, were invited to the exercise.
In late August 2018, Russian Defense Minister Sergey Shoygu said the exercise will be the largest to be held in Russia since “Zapad-81” held by the Soviet Union in 1981. The Zapad exercises in 1981 involved about 100,000 to 150,000 troops and were the largest Soviet military exercises ever held. Shoygu later reported that nearly 300,000 troops would be taking part in the drills along with 36,000 vehicles and 1000 aircraft. 80 warships are also involved in the exercise. Vostok 2018 was double the size of the previous exercise in the region, Vostok 2014.
