Carpathian Military District
After the war, the tank and mechanized corps were re-rated as divisions. During the reforms of 1956–58, most of the corps were again disbanded to create the new combined arms and tank armies. A few corps were nevertheless retained, of both patterns. The Vyborg and Archangel Corps of the Leningrad Military District were smaller armies with three low-readiness motorized rifle divisions each. The Category A Unified Corps of the Belarussian Military District (Western TVD/Strategic Direction) and Carpathian Military District (also Western TVD) were of the brigade pattern.
