Program Executive Office, Combat Support & Combat Service Support The Program Executive Office, Combat Support & Combat Service Support provides centralized oversight for acquisition, sustainment, and modernization of sustainment-related materiel and systems supporting United States Army formations. It aligns programs of record with force modernization priorities established by Department of Defense, Office of the Secretary of Defense, and Joint Chiefs of Staff directives while coordinating with combatant commands such as United States Central Command, United States European Command, and United States Indo-Pacific Command. The office integrates lifecycle management from initial concept through fielding and retrograde in support of operations like Operation Iraqi Freedom, Operation Enduring Freedom, and multinational exercises such as NATO Resolute Support.

Overview

PEO CS&CSS executes portfolio management across domains including logistics, sustainment, medical materiel, and engineer support, interfacing with organizations such as Army Materiel Command, U.S. Army Acquisition Support Center, and Program Executive Office Soldier. It supports doctrine and policy promulgated by United States Army Training and Doctrine Command and aligns requirements with Combatant Commands and the Army Futures Command modernization priorities. The office's responsibilities intersect with statutory frameworks including the Federal Acquisition Regulation and authorities stemming from the National Defense Authorization Act.

Organizational Structure and Leadership

The office reports to leaders in United States Army Materiel Command and is led by a Program Executive Officer, who coordinates with Deputy PEOs, Product Managers, and Life Cycle Managers drawn from organizations like Ordnance Corps, Transportation Corps, and Quartermaster Corps. Leadership interacts regularly with officials from Office of the Secretary of Defense, Assistant Secretary of the Army for Acquisition, Logistics and Technology, and congressional oversight committees such as the House Armed Services Committee and the Senate Armed Services Committee. The staff includes acquisition professionals certified under the Defense Acquisition Workforce Improvement Act and liaises with career fields represented by Acquisition Corps and Sustainment Center of Excellence.

Program Portfolio and Major Systems

The portfolio encompasses major systems for sustainment, including vehicle recovery and maintenance platforms, land bridge logistics systems, medical evacuation and medical materiel suites, tactical power generation, water purification, and facility maintenance equipment. Programs coordinate with system integrators and suppliers from the defense industrial base including primes like General Dynamics, BAE Systems, Lockheed Martin, and Raytheon Technologies, and specialty firms such as Humvee manufacturer AM General and Navistar Defense. Major fielded systems intersect with platforms like the M1 Abrams, M2 Bradley, Stryker, and support elements used in Expeditionary Sustainment Command operations. The office manages contracting vehicles and program baselines that affect programs across Joint Light Tactical Vehicle and retrograde logistics for theater drawdown.

Acquisition and Procurement Processes

Acquisition processes adhere to milestones and acquisition categories dictated by Department of Defense Instruction 5000.02 and leverage contracting mechanisms such as indefinite delivery/indefinite quantity, other transaction authority, and firm-fixed-price contracts overseen by Defense Contract Management Agency. Procurement engagements require coordination with Defense Logistics Agency for cataloging and with Defense Acquisition University for workforce training. Program officials testify before oversight bodies including the Government Accountability Office when audits or program inquiries arise, and they implement corrective actions driven by findings from Congressionally Directed Reports.

Research, Development, Test, and Evaluation

RDT&E activities are conducted with partners from U.S. Army Combat Capabilities Development Command, U.S. Army Medical Research and Development Command, and test centers such as Aberdeen Test Center and Yuma Proving Ground. The PEO oversees developmental testing and operational testing with U.S. Army Test and Evaluation Command coordination, applying lessons from exercises like Joint Readiness Training Center rotations and evaluations during Project Convergence events. Collaboration extends to federally funded research entities including Defense Advanced Research Projects Agency, national laboratories like Sandia National Laboratories and Oak Ridge National Laboratory, and academic partners such as Massachusetts Institute of Technology and Georgia Institute of Technology.

Partnerships and Industry Collaboration

The office engages industry partners, prime contractors, small businesses, and original equipment manufacturers under initiatives linking Small Business Innovation Research and Small Business Technology Transfer programs. Public–private collaborations involve logistics firms, component suppliers, and defense consortia, coordinated through outreach events at venues such as Association of the United States Army conferences and Defense Innovation Unit engagements. International collaboration occurs with allies and partners via programs tied to NATO Support and Procurement Agency frameworks and foreign military sales agreements with nations including United Kingdom, Australia, and Germany.

Operational Impact and Deployments

PEO CS&CSS programs deliver systems that enable sustainment operations in contingency deployments, humanitarian assistance missions like responses to Hurricane Katrina and pandemic support during COVID-19 pandemic, and persistent theater logistics in support of operations in Iraq and Afghanistan. Program outputs affect readiness metrics tracked by U.S. Army Combined Arms Support Command and sustainment doctrine promulgated by Army Sustainment Command. Fielded capabilities reduce logistics tails, enhance medical evacuation timelines, and improve materiel readiness for units participating in multinational operations such as Operation Atlantic Resolve and Pacific Pathways.
