Group army (military unit)
Group armies (simplified Chinese: 集团军; traditional Chinese: 集團軍; pinyin: jítuán jūn) or army groups or combined corps, which are corps-level military formations of the People's Liberation Army Ground Force of China.
Some may use or translate 'Group Army' loosely to mean the same as Army Group through various time periods of history, depending on whether the military formation is under Nationalist China (ROC) or Communist China (PRC). Chinese Army Group or Group Army could be equivalent to field army or army group in other militaries but not necessarily so. This is because while“ 军” in Chinese means "corps" when classifying by size or number of troops, it also means (and more frequently so) in common and less precise military usage - any significant grouping of combat troops / i.e. army (usually corps size or larger; including Army or Army Group as per defined by most international military forces).
