What does a Coordinated Fire Line (CFL) function as in fire support coordination?

• A. A line along which fires may be exchanged to prevent fratricide and ensure coordination.
• B. A restricted boundary where no fires are allowed.
• C. A route for moving friendly forces across the battlefield.
• D. A pre-planned target area for artillery.

Answer: (A)

A Coordinated Fire Line is a boundary used in fire support coordination that allows fires from adjacent units to be exchanged along the line to prevent fratricide and keep fires properly synchronized. As two units maneuver near each other, firing units can shift or share fire support across the CFL so targets near the boundary can be engaged quickly without risking friendly troops. This shared line creates a clear, deconflicted space where artillery, mortars, and close air support can be coordinated to support the assault while maintaining safety for both sides. It’s not a no-fire boundary, a route for movement, or a pre-planned target area—it's a boundary that enables coordinated, exchangeable fires between adjacent units.
