Mandates an annual unclassified report (with possible classified annex) to the Senate and House Armed Services Committees by March 1, detailing identified properties, changes since the last report, and recommended actions.
Defines “foreign adversary” using the definition from the Secure and Trusted Communications Networks Act, covering foreign governments, agents, partnerships, and corporations.
Specifies that “vicinity” means land adjacent to a base or within 10 miles of its boundary, and excludes certain contingency overseas locations.
