Which group in the NSW is affiliated with reserve operations?

In the context of the Navy Special Warfare (NSW), Group 11 is specifically associated with reserve operations. This group is tasked with the organization, training, and deployment of reserve Special Operations personnel. By focusing on utilizing reservists, Group 11 ensures that the NSW can leverage a diverse range of experiences and skills beyond those of active-duty members. This affiliation allows for an operational flexility, as reservists can be mobilized to support active-duty operations when necessary, thus enhancing the overall capability of the NSW.

The other groups within NSW, while integral in their roles, are primarily composed of active-duty personnel or have different operational focuses that do not center around reserve operations. Therefore, the distinct purpose of Group 11 in relation to reserve activities makes it the correct answer in this context.
