What is an example of a condition requiring boresight in military operations?

Boresighting is an essential procedure typically required when weapons systems, particularly those that involve optics or precision targeting, need to be accurately aligned to ensure effective engagement of targets. A hard landing can result in significant impacts that may misalign the targeting systems of vehicles or aircraft, necessitating a boresight to restore precision. When a hard landing occurs, the physical stresses can displace or misalign critical components, meaning that targeting systems may no longer be accurately zeroed in on the intended point of impact or aim. Conducting a boresight in this scenario ensures that any misalignments caused by the landing are corrected and that the weapon systems are operating as intended for subsequent operations.

In contrast, operational stress, system malfunction, and extended maneuvering do not specifically indicate a need for boresighting in the same direct manner as hard landings. While these issues might affect operational readiness or performance, they do not necessarily lead to the misalignment of targeting systems in the way that a hard landing typically would.
