What is range to effect and how is it used?

• A. The distance from aircraft to target
• B. The distance from observer to target used for delivery calculations and assessing potential collateral damage
• C. The distance between two targets
• D. The range of radio communications

Answer: (B)

Range to effect is the distance from the observer to the target used to calculate how a weapon will deliver its intended effect and to judge the potential collateral damage. This distance is what ties your position on the ground to the strike’s outcome, shaping ballistic calculations, time of flight, and the size of the weapon’s impact or blast area. By knowing this range, you can select the appropriate munition and fuze settings to ensure the target is hit with the desired effect while minimizing risks to nearby noncombatants or sensitive assets. It’s distinct from the aircraft-to-target distance or the distance between targets, and it’s not about radio communication range.
