Full-spectrum operations is the U.S. Army's core idea about how to conduct operations on land — its operational concept. Field Manual (FM) 3-0, Operations, emphasizes that conflict involves more than combat between armed opponents. Full spectrum operations apply combat power through simultaneous and continuous combinations of four elements: offense, defense, stability, and civil support. The Army must defeat enemies and simultaneously shape the civil situation through stability or civil support operations.
