It serves as a guide on how United States Army Materiel Command and Army Contracting Command and its subordinate contracting support brigades and battalions are organized, deploy, and support deployed Army forces. It also provides detailed information regarding how Army Contracting Command and its subordinate structure can lead the contracting support planning and coordination effort for the Army, and, when directed, for the joint force commander. Finally, this publication provides additional information on other Army expeditionary contracting and contract support-related capabilities such as the United States Army Corps of Engineers, the United States Army Intelligence and Security Command, the Logistics Civil Augmentation Program, the United States Army Health Contracting Activity, and the Assistant Secretary of the Army for Acquisition, Logistics, and Technology forward support teams, along with the integration of these capabilities into the overall contracting support effort in a designated operational area.

Contested Logistics Industry Week (CLIW) Speech - In a speech Friday, 20 September 2024, MG Michelle Donahue, Commanding General of U.S. Army Combined Arms Support Command, discussed the future of Army Sustainment within the context of Contested Logistics with over 300 industry partners and sustainment leaders. She emphasized a holistic approach to modernization and the importance of a comprehensive approach that includes people, processes, data, and technology. She echoed Chairman Brown's need for an integrated approach to logistics, with efforts not siloed and effective solutions shared among different entities. Sustainment modernization efforts are focused on precision sustainment, predictive logistics, autonomous technologies, and demand reduction. The Army must have the ability to protect, preserve, and regenerate combat power on a transparent battlefield against a formidable adversary and set the theater in a land-based and maritime environment, enabled by dynamic decision-making, while conducting multi-functional and multi-modal sustainment operations.
