OB 2cm Flak is a military bunker located in Norway, part of the country's extensive Cold War-era fortifications. During the Cold War, Norway's strategic position near the USSR led to the construction of numerous military bunkers and secret bases as part of its national defense strategy. These structures were designed to protect against potential Soviet aggression and to maintain Norway's sovereignty in a tense geopolitical climate.
The bunker's specific function as a 2cm Flak (anti-aircraft) position highlights its role in air defense during this period.
