During the Second World War, the Soviets had by far the best airforce between the two belligerants, and in order to deploy its aircrafts on the battlefield a Commander was able to construct an Airfield.
The Air Field was a landing strip with a flight control tower and an armory with a fuel dump, constructed by the Soviet Union. They were used to maintain aircraft that required a runway in order to land, the Yak-9 attack planes and their MiG fighter jets. The Airfield also allowed for calling in paratroopers or parabombs onboard the Badger bombers.
After the war, the Soviet air force was almost completely destroyed, and such these structures were not seen again until WWIII, where a new design entered service.
