Land Warrior - Coming to a Grunt Near You: WASHINGTON -- The Land Warrior system may not be fashionable, but it's what the well-dressed infantryman will fight in. Members of Congress and their staffs got a chance to see what well-dressed grunts will wear during a May 3 demonstration of the Land Warrior technology at the Rayburn House Office Building here. The system designed by Army researchers based in Natick, Mass., is aimed at making service members more lethal on future battlefields.
