What is the function of a Fire Support Coordination Line (FSCL)?

• A. To deconflict fires between different units by establishing a boundary that requires coordination to cross.
• B. To designate airspace control.
• C. To assign targets to units.
• D. To measure weather influences.

Answer: (D)

A Fire Support Coordination Line defines a boundary that helps deconflict fires between units by requiring coordination before fire support crosses it. This boundary prevents uncoordinated fires from entering a neighboring unit’s area and ensures that any cross-boundary fire is planned and cleared through the proper command channels. It’s not about airspace control, target assignment, or weather measurement, which are handled by other systems and processes.
