A Group Army (集團軍 in traditional Chinese /集团军 in simplified Chinese; jituan jun), is a major Chinese formation. Some may use or translate it loosely to mean the same as Army Group and through various time periods or 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).
