The 750th Tank Battalion in the ETO poured reinforced concrete on its glacis had to use jackhammers at the end of hostilities to remove six inches of the stuff. Experiments conducted by the 709th Tank Battalion in February 1945 indicated that poured concrete did not stop bazookas from penetrating the armor plate, but that it did reduce the splash of molten steel inside the tank caused by the warhead to �negligible� proportions. Based on combat experience, tankers in the 753d Tank Battalion concluded that antitank rounds that hit concrete-reinforced armor had a reduced chance of killing the crew, even if they knocked the tank out of action.
