What is the first step in creating a Range Card?

The first step in creating a Range Card involves the gunner laying beside the gun and setting sights. This action is crucial because establishing a proper aiming reference ensures that the gunner has a clear and accurate point from which to measure and record details on the Range Card. By setting the sights correctly, the gunner can determine the range to various target points accurately, which is essential for effective range estimation and coordination during operations.

The other actions, while important in their own contexts, do not directly initiate the creation of a Range Card. For instance, walking a pace count is typically associated with estimating distances during navigation rather than the specifics of preparing a Range Card. Marking a distance in defilade is necessary but comes after the initial steps of establishing the aiming point. Laying the gun on the aiming point is also a vital component but typically follows the establishment of the sight settings. These subsequent actions depend on the foundation established by the gunner's initial setup.
