What does GTL help determine in targeting?

• A. Imaginary straight line from gun to target
• B. Imaginary line from target to observer
• C. Vertical line to target
• D. Range to target

Answer: (A)

GTL represents the gun-target line—the imaginary straight line from the firing weapon to the target. It defines the direction of fire, so knowing the GTL lets you establish the correct azimuth and elevation to place rounds on the target. It’s about where the gun is aiming toward the target, not about the target’s line of sight back to the observer, a vertical reference, or the distance alone. The distance (range) to the target is a related measurement but not what the GTL itself determines; GTL is about the fire direction from gun to target.
