Stalin Line, a system of deep defences and deep deployment of troops built during the 1930s deep inside the USSR's Western frontier. Consisting of a series of thirteen fortified regions it was constructed as a springboard for an offensive as well as for defensive purposes. Unlike the
Maginot Line it could not be outflanked on land as it stretched from the Baltic to the Black seas. After the Soviet occupation of eastern Poland in October 1939 it was largely dismantled as it was too far away from the new Soviet border for offensive purposes, and Stalin was no longer thinking in defensive terms.
