Shots fired so high they would miss the targets are prevented from flying beyond the limits of the reservation at Fort Monmouth, Vt., by overhead shields made of steel. The shields, designed by Lt. Claude V. Wadsworth, Signal Corps range officer, are placed so that soldiers fire from beneath them. Any shot that would be more than a foot above the target is defected by striking the shield and the bullet falls to the ground several feet in front of the marksman. The shields safeguard people and animals that may venture near.
