This summary report is one in a series of reports that summarizes key themes and lessons learned from our body of oversight work in several key areas. We offer these summaries to provide helpful and timely information relevant to DoD priorities. To reduce deployment times and enable timely support during initial phases of an operation, the DoD maintains prepositioned war reserve materiel, comprising equipment and supplies in strategic locations around the globe.
We reviewed DoD OIG audit and evaluation reports from the previous 10 years to identify trends and recurring challenges for prepositioned stocks. Specifically, we identified lessons learned in nine DoD OIG reports issued before May 7, 2025, related to the maintenance, accountability, and storage of prepositioned stocks. These lessons learned may help the DoD to avoid or mitigate issues similar to those we identified in our prior reporting.
