This bill proposes an amendment to the National Defense Authorization Act for Fiscal Year 2025, specifically targeting guidance related to the aggregate square footage of Department of Defense facilities. Its primary purpose is to create an exemption from these requirements for military installations undergoing a mission transition as of the date of the bill's enactment. This legislative change would allow such installations greater flexibility by not subjecting them to existing mandates on maintaining the total square footage of their facilities, thereby supporting their adaptation to new operational roles.
