The Chairman of the Central Military Commission is the head of the Central Military Commission (CMC) and the commander-in-chief of the People's Liberation Army (PLA), the People's Armed Police (PAP) and the Militia. The officeholder is additionally vested with the command authority over China's nuclear arsenals.
There are technically two offices with the same name, including the chairman of the Chinese Communist Party (CCP) CMC and chairman of the People's Republic of China (PRC) CMC. However, under the arrangement of "one institution with two names", they function as one office. The officeholder is usually the CCP general secretary; this grants significant political power as the only member of the Politburo Standing Committee with direct responsibilities for the armed forces. According to both the CCP constitution and the state constitution, the chairman assumes overall responsibility over the work of the CMC. Per the chairman responsibility system, all significant issues in national defense and Army building are planned and decided by the CMC chairman, who holds the final deciding vote on major military decisions and oversees the CMC's and the military's leadership and operations. The office confers military ranks, though regulations stipulate that no military rank shall be conferred on the chairman themselves.
