Name one category of personnel who are considered as isolated.

Individuals missing in action (MIA) are categorized as isolated personnel because they are service members whose status is unaccounted for following a military operation. This classification reflects the uncertainty surrounding their whereabouts, and they are often presumed to be either captured or in a situation where they are unable to communicate their status.

The MIA designation is significant in the context of personnel recovery because it indicates that these individuals require specific recovery efforts to ascertain their fate and potentially bring them back to safety. The military places a strong emphasis on locating and recovering MIAs as part of their commitment to service members and their families, which underlines the importance of this category within military operations and strategies.

In contrast, the other options do not fit the definition of isolated personnel in the same way, as comrades in arms refer to fellow service members who are typically not isolated, support staff generally refers to those providing assistance but not in isolation, and doctors and medics are part of the operational framework rather than categorized as isolated individuals.
