Contrast the frugality intended by the Ordnance Dept. by one company commander who planned his attack on a German fortified (field fortification) position in the woods. He had all four platoons open up and the tanks advanced under suppressive infantry fire. The tanks then began opening up and a platoon moved forward and took up a new firing position. Then the next platoon until the last. All this time units not moving and the tanks poured supressive fire onto the Germans. Finally, one platoon flanked the German pillboxes and forced their surrender. The company rolled up the German line but used up all the battalion, then regiment and then division's allotment of ammunition. The supply officer came out to investigate the heavy usage and the company commander told them they were capturing a fortified German position with minimal casualties. Any problem? No. It saved lives and surprised the Germans who tought they would repel or inflict heavy casualties on the attacking Amis. Read that in the book Battle Hardened.
