Army groups of the National Revolutionary Army

The army groups of the National Revolutionary Army were the largest standing field formations of the Chinese army under the Republic of China during the Second Sino-Japanese War. The first were set up in July 1937, right after fighting broke out at Marco Polo Bridge, and more were created as the war went on. Each army group normally commanded two or more field armies or several corps, together with assorted smaller units, which made it roughly comparable to an army in British or American usage. Above it stood only the geographically defined military regions, since the few army corps that existed were formed briefly for the Battle of Wuhan. By the end of the war with Japan some forty army groups existed, and three more were raised and dissolved during the Chinese Civil War as the army corps took over their role. Sources list the groups together with their organization, commanders and notable battles, and some commanders are marked as killed in action.
