To amend the Military Land Withdrawals Act of 2013 to withdraw and reserve certain public land in the vicinity of Yuma Proving Ground, Arizona.

This bill amends the Military Land Withdrawals Act to permanently withdraw approximately 22,000 acres of public land near the Yuma Proving Ground in Arizona from general entry, mining, and leasing. The withdrawn land is reserved for military readiness and security, with management responsibilities shared between the Secretary of the Interior and the Secretary of the Army. While the land remains available for conservation, recreation, and hunting, any non-military uses or leases require the consent of the Army to ensure mission compatibility. The withdrawal is indefinite but can be terminated if the Army determines the land is no longer needed for military purposes.
