Which statement about BCL is true?

• A. USMC specific FSCL
• B. A general boundary for airspace coordination
• C. A line used to bound ground troop movements
• D. A target designation boundary

Answer: (A)

BCL is a Marine Corps–specific Fire Support Coordination Line. It defines the boundary within which Marines coordinate and execute fire support, aligning with the FSCL concept to prevent fratricide and deconflict fires with adjacent units. That’s why the correct statement is that BCL is USMC specific FSCL. It isn’t a general boundary for airspace coordination, a line used to bound ground troop movements, or a target designation boundary, which is why the other options don’t fit.
