The 3rd Army (Romanian: Armata a 3-a) was a field army of the Romanian Land Forces active from 1916 to the 1990s. It fought as part of the German Army Group B during World War II, in Ukraine, the Crimea, and the Caucasus. General Petre Dumitrescu commanded the 3rd Army for much of that time.
The 3rd Army contained the only Romanian divisions trained by the Germans, and as a result, it was a significantly better fighting force than the fellow 4th Army during the Battle of Stalingrad.
