35th Expeditionary Signal Battalion

• World War II Origins: The 35th Signal Battalion was originally constituted on 11 May 1942 in the Army of the United States as the 35th Signal Construction Battalion. • European Theater Service: The unit participated in several major campaigns during World War II, including Normandy, Northern France, Rhineland, Ardennes-Alsace, and Central Europe. • Post-War Inactivation and Reactivation: After World War II, the battalion was inactivated in December 1945, but later reactivated in the U.S. Army Reserve, showing its enduring legacy. • Signal Expertise: Specialized in providing tactical communications support, the unit has adapted through decades of technological change, from field wire to satellite communications. • Transformation to Expeditionary: Redesignated as the 35th Expeditionary Signal Battalion in 2006, the unit updated its mission to support modern, rapidly deployable operations. • Global Deployments: Members of the 35th have deployed in support of Operations Enduring Freedom and Iraqi Freedom, providing vital communications links for combat and support units. • Hurricane Katrina Response: In 2005, soldiers from the 35th helped support disaster relief operations after Hurricane Katrina, demonstrating their versatility in both military and humanitarian missions. • Innovation in Communications: The battalion has been at the forefront of integrating new communications technology, including secure internet and radio systems, for the Army Reserve. • Unit Insignia: The battalion’s distinctive unit insignia features a gold lightning bolt—symbolizing speed and power in communications—over a blue background. • Community Engagement: Headquartered in Fort Allen, Puerto Rico, the 35th ESB is active in local events and partnerships, strengthening ties between the Army Reserve and civilian communities.
