High Quality Content by WIKIPEDIA articles! The People`s Liberation Army has not always used ranks or insignia. In common with the practice of the Red Army at the time of its founding in 1927, neither were used until 1955 when a system of ranks was established. As a result of the Cultural Revolution, ranks were abolished in May 1965. After the Sino-Vietnamese War of 1979, reforms in the PLA began to be made to professionalize the armed forces once more. The 1984 Military Service Law provided for the resumption of rank, but disagreements on what ranks were to be used and who would receive them caused the revival of rank to be delayed until 1988.
