Which document governs the lawful and policy-compliant use of force, including engagement criteria and constraints, in air operations?

• A. ACO
• B. ATO
• C. ROE (Rules of Engagement)
• D. COP

Answer: (C)

Rules of Engagement define when and how force may be used, translating political objectives and legal obligations into actionable guidance for air operations. They establish who may be targeted, under what circumstances, and what level of force is permitted, incorporating engagement criteria, escalation procedures, and prohibitions to ensure actions comply with national and international law as well as policy. In air operations, this makes ROE the authoritative reference pilots and controllers rely on to conduct engagements lawfully and responsibly, balancing mission goals with civilian safety and legal constraints.

By comparison, an Air Tasking Order schedules and assigns missions and timing, a Concept of Operations outlines how operations will be conducted at a high level, and an Airspace Coordination/Control document focuses on managing airspace and coordination. None of these dictate the legal and policy constraints on force the way ROE do.
