The Pakistani military largely retained British military traditions and doctrine until 1956, when the United States dispatched a specialized Military Assistance Advisory Group to Pakistan to build its military; from this point onward, American military tradition and doctrine became more dominant within Pakistan's armed forces. In March 1956, the order of precedence of the Pakistani military's three formal services changed from "Navy-Army-Air Force" to "Army-Navy-Air Force". In the 1990s, additional reforms of the military eventually changed the order of precedence to "Army-Navy-Air Force-Marines"; though the Marines fully remained part of the Navy and did not function as a separate service branch as is the case with the U.S.
