The purpose of this legislation, known as the Expanding Defense Community Partnerships Act, is to enhance the ability of the Department of Defense (DoD) to enter into agreements with state, local, and tribal governments. These agreements, called intergovernmental support agreements, allow for collaboration in providing various support services related to military installations. Key provisions of the Act include several changes to existing laws. First, it allows the DoD to partner with other federal agencies when entering into these agreements, broadening the scope of potential collaboration.
