Which document was mentioned as a resource for developing an AT plan?

The correct choice refers to DoDi 2000.12, which is a Department of Defense Instruction that provides guidance on the implementation of anti-terrorism programs. This document outlines the necessary policies, procedures, and responsibilities for developing and executing an anti-terrorism (AT) plan, making it a crucial resource for any organization or individual tasked with creating such a plan. It emphasizes the importance of establishing a comprehensive approach to recognizing and mitigating threats, ensuring that all actions taken are aligned with federal standards and expectations.

While other options may contain relevant information on emergency response or regulations, they don’t specifically focus on the creation of anti-terrorism plans in the same structured manner that DoDi 2000.12 does. For an ATO, the instruction serves as an authoritative framework, providing clarity and direction essential for effective anti-terrorism strategies.
