CORVUS — the eyes and ears of III Marine Expeditionary Force.

The 3rd Radio Battalion is a United States Marine Corps signals intelligence (SIGINT) and electronic warfare unit assigned to III Marine Expeditionary Force (III MEF) in the Western Pacific. Operating under the CORVUS designation, 3rd Radio Battalion provides critical intelligence support to Marine commanders by intercepting, analyzing, and exploiting enemy electronic communications and emissions. The battalion's Marines are trained specialists in cryptologic linguistics, signals analysis, electronic warfare, and cyber operations — the invisible warriors who provide the intelligence advantage on the modern battlefield.

Stationed in the Pacific theater, 3rd Radio Battalion operates at the front edge of America's strategic competition in the Indo-Pacific region. The battalion's personnel deploy with Marine ground forces, providing tactical SIGINT support during exercises, contingency operations, and real-world intelligence collection missions. The CORVUS callsign — derived from the Latin word for raven, a symbol of intelligence and watchfulness — reflects the battalion's role as the silent sentinel that monitors enemy communications and provides commanders with the decision-quality intelligence they need to outmaneuver adversaries.

Perfect For: 3rd Radio Battalion veterans and active-duty Marines, signals intelligence professionals, III MEF alumni, electronic warfare specialists, cryptologic linguists, and military patch collectors who appreciate the covert side of Marine Corps operations.

CORVUS watches — the enemy never sees 3rd Radio Battalion coming.
