Which document is responsible for implementing the Air Force Installation and Mission Support Command (AFIMSC)?

The correct choice, PAD 14-04, is pivotal because it serves as the official directive that outlines the establishment and implementation of the Air Force Installation and Mission Support Command (AFIMSC). This document establishes the AFIMSC's mission, functions, and responsibilities, ensuring that the command operates within the framework set by the Air Force. Furthermore, it provides guidance on how the organization should be structured and how it aligns with other Air Force initiatives and commands.

Other documents, like the AFIMSC Directive, AFI 90-901, and AFMAN 33-363, while potentially related to broader Air Force policies and guidance, do not specifically focus on the implementation details of AFIMSC. Thus, they do not fulfill the same function as PAD 14-04 in terms of establishing the command’s operational framework.
