Who are members assigned to active-duty units that complete their training within that unit?

The correct answer pertains to Individual Mobilization Augmentees (IMAs), who are members assigned to active-duty units. IMAs are unique in that they complete their training and perform their duties within their assigned active-duty unit, allowing them to integrate into the unit’s operational environment seamlessly. This training typically occurs alongside the active-duty personnel, ensuring that IMAs are well-prepared for their roles when called upon to augment the unit's capabilities.

In contrast, the other categories described do not fit this specific scenario as they have different roles and responsibilities. Drill Status Guardsmen are primarily part of the reserve component and often perform training on a part-time basis without the same integration into an active-duty unit. Active Guard Reserve members, while serving in full-time roles in support of reserve units, do not complete their training within a specific active-duty unit like IMAs do. Air Reserve Technicians, although they play vital roles in the reserve component, may not necessarily train within active-duty units as their primary focus is on maintaining the readiness and operational capability of the reserve forces. Thus, the definition and alignment with the completed training within an active-duty unit make Individual Mobilization Augmentees the correct choice.
