What type of report focuses solely on significant readiness changes?

The correct answer focuses on the concept of documenting specific alterations in readiness. A change report is designed to highlight and communicate significant shifts or modifications in the status of readiness. This can include changes in personnel, equipment availability, or mission capability that are critical for decision-makers. By centering exclusively on these alterations, the change report provides stakeholders with a clear picture of current readiness without the distraction of routine data that may be included in other types of reports. This focused approach allows for more efficient management and response to evolving circumstances in readiness levels.

In contrast, other report types may include broader information. A regular report typically covers ongoing operational status over time, incorporating various aspects of performance and readiness but not solely focusing on significant changes. A validation report generally assesses the accuracy or integrity of data rather than identifying changes per se. A deployed report deals with information gathered from units currently on deployment, which may also not concentrate specifically on significant changes in readiness.
