The 2nd Tatsinskaya Guards Tank Corps was a Red Army armoured formation that saw service during World War II on the Eastern Front. After the war it continued to serve with Soviet occupation forces in Central Europe. It was originally the 24th Tank Corps. The unit had approximately the same size and combat power as a Wehrmacht Panzer Division, and less than a British Armoured Division had during World War II. Members of the corps committed the notorious Nemmersdorf massacre, torturing and killing tens of German civilians in October 1944.
