How do you blast through the obstacles and minefields on the beaches Normandy? How do you get thousands of tonnes of tanks, guns, and men into the fight? And what about reopening the shattered French ports? You need men who are as skilled in construction as they are destruction. You need the engineers.

Several weeks after the invasion of Normandy began, the Allies finally take a port city there, though the actual harbor has been destroyed. On Saipan the Americans have the advantage, in Finland, the Soviets do, but the big news is the Soviet destruction of huge chunks of German Army Group Center, demolishing entire Army Corps, and surrounding tens of thousands of the enemy.
