A large step toward Information Age war-fighting was completed in March at the Army's National Training Center (NTC), Fort Irwin, Calif. The Army's Experimental Force (EXFOR)-the world's first digitized ground force, the 1st Brigade, 4th Infantry Division (Mechanized)-deployed to the harsh conditions of the Mojave Desert at Ft. Irwin for an intensive, realistic war-fighting exercise against the NTC's vaunted Opposing Force (OPFOR), the 11th Armored Cavalry Regiment. The exercise was the culminating event of the TF XXI Advanced Warfighting Experiment (AWE)-a key part of the Army's Force XXI process of continuous experimentation and transformation which will result in Army XXI-the digitized force for the 21st Century.
