This bill modifies how the Department of Defense can pay for and manage agreements with state and local governments to provide support services at military installations. It expands the funding sources the Pentagon can use to pay for these intergovernmental support agreements, allowing them to draw from any DOD appropriation rather than just specific funding streams. The bill requires the Secretary of Defense to create a uniform framework for collecting data on all such agreements within 180 days and establish a publicly searchable database within one year, then conduct analyses every four years examining which installations use these agreements, what services they cover, and any barriers to their use. The Secretary must submit reports to Congress every four years with findings, recommendations for improving the program, and best practices for working with local communities. This legislation affects military installations nationwide and the state and local governments that partner with them to provide services like facility maintenance and construction.
