(U) The purpose of this concept is to establish doc- trine and procedures for providing signals intelligence (SIGINT: support to military commanders in all circumstances under which military forces are expected to be employed. The concept applies to those SIGINT resources which are included within the Consolidated Cryptologic Program (CCP) and to those resources which have been specifically designated as SIGINT activities by the Secretary of Defense, wherever programmed. Planning for SIGINT support to military commanders will be in consonance wit! this concept. : 7 ° “SECTION 2 — EXPLANATION OF TERMS . esos . 2. e3- Communications Intelligence (COMINT) - Technical . and intelligence information derived from foreign communication: by other than the intended recipients.
