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. We reviewed DoD OIG audit and evaluation reports from the previous 10 years to identify trends and recurring challenges during contingencies and other DoD operations.
We identified lessons learned in six previously issued DoD OIG reports related to burden‑sharing
with international partners; specifically, the lack of proper reimbursement by international
partners for supplies and services provided by the DoD. These audit and evaluation reports
document that the DoD may have provided at least $268.1 million in supplies and services
without assurance that it was reimbursed by international partners.
