Which item listed is a Mission Coordination Measure (MCM)?

• A. Boundaries
• B. FSA/FSS
• C. MFP
• D. PLs

Answer: (B)

Mission Coordination Measures are the specific, mission-focused constraints that tie fire support to the current maneuver and deconflict it with adjacent elements. A Fire Support Area (FSA) and its counterpart Fire Support Sector (FSS) are classic examples of MCMs because they designate where fires may be employed and how those fires will be integrated with the unit’s scheme of maneuver. This geographic control directly coordinates fires with the mission, making it the best fit for what an MCM represents.

Boundaries, while important for deconfliction, are a broader FSCM concept and not the defined MCM in this context. A Master Fire Plan is the overall plan for employing fires, not a single coordination measure. Phase Lines are control lines used for movement and sequencing; they support coordination but aren’t the MCM designation referenced here.
