In military [[telecommunication]]s, the term '''Electronic Support''' (ES) is the division of [[electronic warfare]] involving the actions taken under direct control of an operational commander to search for, [[intercept]], identify, and locate sources of radiated electromagnetic energy for the purpose of immediate [[imminent threat|threat]] recognition. Thus, Electronic Support (ES) provides a source of [[information]] required for immediate decisions involving [[Electronic Protection]] (EP), [[Electronic Attack]] (EA), avoidance, targeting, and other tactical employment of forces. Electronic Support [[data]] can be used to produce [[signals intelligence]] (SIGINT), both [[communications intelligence]] (COMINT) and [[electronics intelligence]] (ELINT).
