SOT-A
A SOT-A (Special Operations Team-Alpha) is a signals intelligence–electronic warfare (SIGINT-EW) element of the United States Army Special Forces.[1][2][3][4][5]
They are low-level SIGINT collection teams that intercept and report operational and technical information derived from tactical threat communications through prescribed communications paths. The mission of a SOT-A is to conduct SIGINT/EW in support of information operations (unilaterally or in conjunction with other Special Operations Forces (SOF) elements) to support existing and emerging SOF missions worldwide.[1][3][5]
SOT-A's are the direct descendants of the Army Security Agency's Special Operations Detachments (USASASODs).[1][5]
