2-12. When commanders destroy, they apply lethal combat power on an enemy capability so that it can no longer perform any function. Destroy is a tactical mission task that physically renders an enemy force combat-ineffective until it is reconstituted. Alternatively, to destroy a combat system is to damage it so badly that it cannot perform any function or be restored to a usable condition without being entirely rebuilt (FM 3-90-1). An enemy cannot restore a destroyed force to a usable condition without entirely rebuilding it.
