Title 10 › Subtitle A — General Military Law › PART I — ORGANIZATION AND GENERAL MILITARY POWERS › CHAPTER 16 — SECURITY COOPERATION › SUBCHAPTER IV — SUPPORT FOR OPERATIONS AND CAPACITY BUILDING › § 331

Last updated Sep 22, 2026|Official source

Summary

Allows the Secretary of Defense to give help to friendly foreign countries for certain military or stability operations. The Secretary must pick which operations qualify and must tell the appropriate Congressional committees when an operation is designated or when a designation is continued after an annual review. The Secretary of State must agree before help is given. The help cannot break any other law. There are yearly money limits: $450,000,000 total for most logistics, training, and small construction; and $5,000,000 for special interoperability or nonmilitary agency logistics. Help can include logistics, supplies, and services (basic support for moving, supplying, and maintaining forces); buying equipment to loan to partners; specialized training, including before deployment; and small construction tied to a partner’s ability to take part in the operation and limited to the operation area. If a construction project is over $750,000, Congress must be told the location, project title, cost, a DoD Form 1391, and a master plan. If the United States is not taking part in the operation, the Secretaries of Defense and State must jointly certify to Congress that the operation serves U.S. national security, wait 15 days after that certification, and send a report describing the operation, area, countries involved, support to be provided and its duration, how it serves U.S. security, who the partner is fighting and whether those entities are covered by any authorization for use of force, plus any other important details.
