Description:Army medical personnel may not sleep much in their line of work, but when they do, they'll hit the sack in new, ultra-modern dormitories now being built at Fort Sam Houston in San Antonio, the planned new home of the Army's Medical Education and Training Campus. The complex is to become the center of medical training for the entire U.S. military but is only a small part of an eventual $2-billion effort to upgrade and expand the entire base, one of the Army's oldest active installations.
