Co. B 240th Sig Bn Calif. Army National Guard

Company B, 240th Signal Battalion, California Army National Guard, played a vital role in providing communications support within the state and for federal missions. Established during the Cold War era, the 240th Signal Battalion was tasked with maintaining and operating tactical communications systems essential for command and control. Company B, headquartered in Southern California, regularly participated in state emergency responses, field training exercises, and annual training rotations. The unit was eventually inactivated as part of Army National Guard force restructuring in the early 21st century, with its mission and lineage absorbed by other signal units.
