Columbia Basin Seattle

The Columbia Basin Seattle military unit was established during World War II as part of the U.S. Army’s efforts to defend the Pacific Northwest from potential threats. Originally tasked with coastal defense, the unit played a key role in organizing anti-aircraft and surveillance operations along the Puget Sound and Columbia River regions. Throughout the Cold War, the unit adapted to new technologies, contributing to regional air defense and emergency response coordination. Today, Columbia Basin Seattle continues its legacy through National Guard and Reserve components, supporting both homeland security and overseas missions.
