1st composite radio company

The 1st Composite Radio Company was a United States Marine Corps signals intelligence (SIGINT) unit established in the early 1950s. Its primary mission was to provide tactical and strategic radio intercept and communications intelligence support to Marine forces, particularly during the Korean War and early Cold War period. The unit pioneered mobile SIGINT operations, utilizing specialized equipment to monitor enemy communications and contribute to battlefield situational awareness. The 1st Composite Radio Company laid the groundwork for modern Marine Corps signals intelligence capabilities before its lineage was carried forward by successor units such as the 1st Radio Battalion.
