Which of the following is NOT a responsibility of the ATTWO?

The correct choice highlights that establishing personnel training is not a responsibility of the Anti-Terrorism Tactical Watch Officer (ATTWO). The ATTWO focuses primarily on tactical operations related to antiterrorism measures, which includes conducting threat assessments to identify potential security risks, leading reaction forces during incidents to ensure a swift and effective response, and overseeing tactical operations to manage and coordinate security efforts during heightened alerts or actual threats.

Establishing personnel training, although important within the context of overall security and readiness, falls more under the purview of command training officers or other personnel dedicated to training and readiness programs. The ATTWO's role is primarily operational and tactical, honing in on immediate responses to threats rather than developing training programs for personnel. This delineation of responsibilities helps to clarify the primary focus of the ATTWO's role in enhancing ship security.
