What does a round landing target or range correct provide a spotting as during a registration?

The concept of a round landing target or range correct during registration is essential for adjusting fire accurately. When a round lands, it provides a clear indication of where the impact occurred in relation to the intended target. This information allows for the identification of whether the rounds are landing over the target, short of the target, or perfectly aligned with it.

By stating "both over and short," the correct answer encompasses the full spectrum of potential results observed during registration. It indicates that the observer can assess the impact points both in front (short) and beyond (over) the intended target area. This detail is crucial since it equips the crew with the necessary data to make precise adjustments to their fire, ultimately leading to effective engagement of the target.

The other options, while they may seem relevant in the context, do not provide the same comprehensive insight into how the round's impacts can inform adjustments. "Target" and "line" imply identification of the impact but lack the explicit connection to the over and short concept that guides the necessary corrections. The term "accurate and sufficient" suggests effectiveness in a different context, yet it does not capture the critical feedback mechanism provided by observing where rounds land concerning the target.
