The Inner Mongolian Army, also sometimes called the Mengjiang National Army, referred to the Inner Mongolian military units in service of Imperial Japan and its puppet state of Mengjiang during the Second Sino-Japanese War, particularly those led by Prince Demchugdongrub. It was primarily a force of cavalry units, which mostly consisted of ethnic Mongols, with some Han Chinese infantry formations.
