Aug. 25, 1961 - The Pentagon today ordered to active duty 76,500 members of the reserve military forces - 46,500 in the Army, 23,600 in the Air Force, and 6,400 in the Navy. Most of the reservists will be called to report by Oct. 1. No Marine reservists were called because the Marine Corps is meeting its increased manpower goals through voluntary enlistments and service extensions. Secretary of Defense Robert S. McNamara (second from left) would not say whether any of the reservists would be sent to Europe. He also declined to indicate whether the reservists could expect to remain in service for a few months or for close to the one-year limitation. "I can't predict the length of the crisis," he observed.
