"The Third Army claimed to have killed, wounded, or captured 1,811,388 German soldiers, six times its strength in personnel. Fuller's review of Third Army records differs only in the number of enemy killed and wounded, stating that between August 1, 1944 and May 9, 1945, 47,500 of the enemy were killed, 115,700 wounded, and 1,280,688 captured, for a total of 1,443,888" quoted from George S. Patton - Wikipedia, the free encyclopedia
Had it not been for political agreements, Patton would of been first into Berlin. Zhukov's army performed much more poorly against the Germans and took far greater time to take objectives within Germany. Zhukov's Army wouldn't of held for even a month up against just the Third Army, much less the entire forces that the US and British had. Likely results would of been the fall of Soviet Russia in 2-3 years or less, no communist China, no communist Cuba, no communist North Korea and not communist Vietnam.
All Zhukov had was armor and numbers and now where near the talent or understanding of three dimensional warfare that Patton had. All that armor really would of meant is a large number of sorties for P-51's outfitted as tank busters.
