The Army is using night-vision equipment to see in the dark as the allies wage tank warfare against Iraq's Republican Guard.
Both sides have night-vision gear, but the state-of-the-art version used by U.S. forces gives them a decisive advantage over Iraqi troops.U.S. tanks are using thermal imagery in their attack on the Republican Guard, a Pentagon official said Tuesday.
Thermal imagery shows a picture of the heat patterns produced by men and machines at distances of several miles. It allows tank drivers and gunners to see through smoke screens and detect the enemy, day or night.
