Which term best describes the ATTWO’s responsibility?

The term that best describes the ATTWO’s responsibility is Tactical Advisor. The ATTWO, or Anti-Terrorism Tactical Watch Officer, plays a crucial role within the framework of shipboard security, particularly in relation to anti-terrorism and force protection. The primary responsibility of the ATTWO is to provide tactical guidance and support to the ship's personnel during security operations and to ensure the effective implementation of the ship’s security plan in response to any threats.

As a Tactical Advisor, the ATTWO evaluates situations to assess risks, advises the commanding officer on appropriate responses, and oversees the execution of security measures. This position requires a thorough understanding of tactics, techniques, and procedures related to anti-terrorism as it relates to naval operations, making the designation of Tactical Advisor the most fitting for the role. The ATTWO must also coordinate closely with other security personnel, which further emphasizes their advisor role in tactical matters.
