What deviation authority is tasked with maintaining a central registry of granted deviations?

The correct answer reflects that the Major Army Command (MACOM) is the authority designated with the responsibility of maintaining a central registry of granted deviations. As a pivotal organizational element, MACOM oversees the adherence to regulations and ensures that deviations from standard procedures are properly documented and tracked. This central registry allows for effective management of deviations, facilitating accountability and traceability throughout the command.

Maintaining a registry is important in order to understand the implications of any deviations and to ensure that they are within the parameters set by higher leadership. This allows for an efficient review process and can assist in future planning and operational readiness.

The other roles mentioned, such as DCS, G-3/5/7 and Senior Commanders, focus on strategic planning or direct command responsibilities but do not specifically hold the authority or responsibility for tracking deviations in a central registry. The ASCC, while it plays a significant role in command structures, is not primarily tasked with maintaining a central registry of deviations either. Hence, MACOM is the designated authority for this specific function.
