Which FSCM allows fires without coordination within a defined geographic area?

• A. Free Fire Area (FFA).
• B. Fire Support Line (FSCL).
• C. Fire Support Area (FSA).
• D. No-Fire Area (NFA).

Answer: (A)

Fire Support Coordination Measures govern how and where fires can be applied in support of maneuver. A Free Fire Area defines a geographic patch where fires may be delivered without coordination with other units or higher headquarters, allowing observers and units to call for and execute fires quickly within those boundaries. This rapid-fire capability is what the question is asking for—fires without the need for prior coordination inside a defined area. Other measures either establish a line or zone that still requires coordination (to prevent fratricide or address safety and control) or prohibit fires altogether in certain areas, so they don’t provide the same unconstrained capability inside a defined location.
