The long-awaited changes in the operational and tactical units of the People’s Liberation Army (PLA) have begun with a formal announcement by President Xi Jinping in April 2017. After initiating major reforms in late 2015 and throughout 2016, the Central Military Commission (CMC), service headquarters, and military regions (now theater commands) have been reorganized resulting in the reallocation of many personnel and the demobilization of an unknown number of active duty personnel. But, as part of the ongoing 300,000 man reduction, even larger cuts in personnel will follow as headquarters and units at corps/army-level and below are eliminated, re-subordinated, or restructured.
