Ready for 'Operation Minuteman'--Maj. Gen. Edgar C. Erickson, seated, chief of the National Guard Bureau, poses at the Pentagon just prior to tonight's start of a test mobilization of the entire National Guard. With the National Guard Head are Maj. Gen. William H. Abendroth, left, U.S. Army, and Brig. Gen. Winston P. Wilson, U.S. Air Force. The "Operation Minuteman" was designed to find out how many of almost 400,000 guardsmen in 5,600 units scattered in 2,400 communities will answer the test call to duty.
