Formal long-term or operational specific support agreements between Services, Department of Defense (DOD), and/or non-DOD agencies governed by DOD Instruction 4000. 19, Interservice and Intragovernmental Support. These agreements, normally developed at the Service Secretariat and governmental agency director level, document funding and reimbursement procedures as well as standards of support between the supplying and receiving Service or agencies. Inter-Service, intragovernmental agreements, while binding Service level agreements, do not connote DOD-level executive agent responsibilities.
