Which regulation has the roles of a logistics platoon leader?

• A. ATP 4-90
• B. ATP 4-90.1
• C. ATP 4-80
• D. ATP 4-90.5

Answer: (D)

This question tests where the logistics platoon leader’s duties are defined in Army doctrine. In the ATP/Publication system, topics are organized with a base publication and narrower subpublications identified by decimals. The specific roles and responsibilities of a logistics platoon leader are outlined in a subpublication dedicated to platoon-level logistics leadership, ATP 4-90.5. That document provides the exact duties, authority, and tasks expected at that level, such as coordinating sustainment activities within the platoon and aligning with higher echelons.

The broader publication in the 4-90 family covers general sustainment concepts and the overall framework, but it does not detail the platoon leader’s specific responsibilities. The other materials in this area address different topics or perspectives, so they don’t define the platoon leader’s role as precisely as ATP 4-90.5 does.
