What is the minimal deviation correction you can send?

• A. 10 meters
• B. 20 meters
• C. 30 meters
• D. 40 meters

Answer: (C)

When adjusting field fire, corrections are given in discrete, reliable steps rather than tiny, continuous shifts. The smallest practical adjustment you can issue is 30 meters because it’s the smallest increment that will produce a dependable change in where the rounds land, once you account for ballistic dispersion, observer measurement limits, and the gun crew’s ability to implement the correction. Corrections smaller than that (like 10 or 20 meters) are typically not as reliable to register on the target area and can require additional messaging, delaying the mission. A larger step, such as 40 meters, is workable but not the minimum needed to begin tightening the effect. So 30 meters represents the minimal, effective deviation correction you can send.
