Карельский фронт
The Karelian Front in the Petsamo-Kirkenes Operation conducted the only successful major military operation ever undertaken in an Arctic environment in modern warfare. The experiences in the conduct of the operation, particularly in terms of organising rear-area services and supply, were considered important to the conduct of the Red Army’s offensive against the Japanese Kwantung Army in Manchuria, and many leading officers were transferred from Karelian Front to the Baikal theatre of war.
