How is the distance to a new point calculated in a shift mission?

In a shift mission, the calculation of the distance to a new point is crucial for effective fire support. The correct approach involves subtracting the known distance from the new distance. This method helps determine the actual change in distance required to adjust fire from the existing target to the new target accurately.

When the known distance is subtracted from the new distance, it provides the precise adjustment needed to engage the new target effectively. This is essential for ensuring that the rounds land on target, minimizing the risk of deviation that can occur if estimations or incorrect calculations are used.

Other methods, such as using an estimated distance or simply adding the range of a previous target, could result in inaccuracies since they do not directly assess the actual distance change or rely on previous data that may not correlate with the new firing solution. Similarly, averaging the distances of adjacent targets does not provide a clear and precise adjustment method for a specific new target, which is critical in a tactical scenario where exact positioning can be the difference in mission success.
