Which individual designates in-process inspection personnel when automated certification rosters are unavailable?

The unit commander is responsible for designating in-process inspection personnel when automated certification rosters are unavailable. This responsibility typically falls within the unit commander's purview, as they are accountable for the readiness and compliance of their unit's personnel and equipment. In situations where automated systems are not functioning, it is essential to have a designated leader who can ensure that inspections are conducted effectively, maintain operational standards, and ensure compliance with safety regulations.

The other roles mentioned do play significant parts in the overall management and oversight of personnel, but the authority to appoint inspection personnel, particularly in the absence of automated systems, specifically aligns with the unit commander's responsibilities. This ensures that the chain of command is maintained and that there is a clear accountability structure in place for inspection tasks.
