About this Unit
The 14th U.S. Army Security Agency Field Station (14th USASA FS) was a key signals intelligence unit during the Cold War era. Activated in the early 1950s, the unit was primarily stationed in Okinawa, Japan, where it played a crucial role in intercepting and analyzing communications from the Asia-Pacific region. The 14th USASA FS supported both tactical and strategic operations, providing vital intelligence to U.S. and allied forces. The unit was later redesignated as part of the 14th Military Intelligence Battalion, continuing its legacy of intelligence gathering and electronic surveillance.
