In July 1973, III Corps became part of the newly established Forces Command and its training, testing, and evaluation mission began to grow. For the remainder of the decade, III Corps would take part in a number of Training and Doctrine Command tests of organizations and tactical concepts, and play a key role in the fielding of new equipment. III Corps units would also participate in major exercises such as Exercise REFORGER (Return of Forces to Germany) and disaster relief operations in the United States and Central America.
