Coalition Support Fund (CSF)

The Coalition Support Fund (CSF) is a financial aid program used by the United States to reimburse allied countries, mainly in regions like Afghanistan and Iraq, for costs incurred while supporting U.S. military operations. It helps cover expenses such as logistics, security, and infrastructure that these partners undertake to assist U.S. efforts. By providing this support, the CSF encourages cooperation and ensures that partner nations can effectively contribute to shared security objectives without bearing the full financial burden themselves.
