The United States Air Force (USAF) has responsibility from beyond the limits of observed fire out to the range limits of Army weapons systems; the Army, secondary responsibility. Even if the USAF can target or observe, the Army may still have to attack the target. Beyond the range limits of Army weapons, the USAF is responsible. (See also suppression.) See FM 6-series. (Army) - campaign SEAD - SEAD operations that are preplanned, theaterwide efforts conducted concurrently over an extended period against air defense systems normally located well behind enemy lines. complementary SEAD - SEAD operations that involve continuously seeking enemy air defense system targets to destroy them. localized SEAD - SEAD operations that support tactical air operations, Army aviation operations, reconnaissance, and the establishment of corridors for Air Force and Army assets.

synchronization matrix - A format for the staff to record the results of wargaming and synchronize the course of action (COA) across time, space, and purpose in relation to the enemy's most likely COA. The staff can readily translate a synchronization matrix into a graphic decision-making product such as a decision support matrix. Each battlefield operating system can develop its own synchronization matrix for more detail on specific tasks. See FM 101-5.
