Claws of Steel — Leo Kessler

This is the fourth in the fictional series The Dogs of War, by Leo Kessler. They had taken the most impregnable fortress in Europe, faced Stalin's cadets in the screaming inferno of the Russian front, and returned with only a handful of survivors. They were Hitler's elite, dedicated, relentless men, for whom death held no fear, Assault Regiment Wotan. Their next mission was a lightening blow at Kursk in the very heart of Soviet Russia. As they advanced across the burning steppes after the fall of Stalingrad, the men of Wotan found the bodies of German soldiers, hanged, tortured, and mutilated, and they swore they would not leave Russian soil until they had taken their revenge.
