The New Fourth Army was a military unit nominally under the banner of the National Revolutionary Army (NRA) of the Republic of China, established in 1937 as part of the Second United Front during the Second Sino-Japanese War. However, in practice, the New Fourth Army was under the exclusive command of the Chinese Communist Party (CCP) and operated independently of the Kuomintang (KMT)'s central military command. Unlike most NRA units, which were directly overseen by the Nationalist Government, the N4A maintained separate political and operational structures aligned with CCP objectives.
