Joint warfare is a military doctrine that places priority on the integration of the various branches of a state's armed forces into one unified command. Joint warfare is in essence a form of combined arms warfare on a larger, national scale, in which complementary forces from a state's army, navy, air, coastal, space, and special forces are meant to work together in joint operations, rather than planning and executing military operations separately.
Its origins can be traced to the 1938 establishment of the Oberkommando der Wehrmacht, the world's first joint higher command structure, though it should not be seen as the same level of "jointness" as U.S. Joint Chiefs of Staff.
