The Soviet offensive into central Germany, what later became East Germany, had two objectives.
The three Soviet fronts had altogether 2.5 million men (including 78,556 soldiers of the 1st Polish Army), 6,250 tanks, 7,500 aircraft, 41,600 artillery pieces and mortars, 3,255 truck-mounted Katyusha rocket launchers (nicknamed 'Stalin's Pipe Organs'), and 95,383 motor vehicles, many manufactured in the US.
