PROLOGUE
A total of two hundred and eight American soldiers served with the 400th USASA SOD (Abn) between 1962 and 1975. The US Army Security Agency assigned the men of this unit both Top Secret classified and covert missions. Their operations were conducted under surreptitious conditions for security reasons. All of the 400th ASA SOD members were three time volunteers: first of all, they volunteered for their U.S. Army assignments; secondly, each had to volunteer and successfully complete the US Army Airborne Training School; and thirdly, each had to volunteer to serve with the new ASA Special Operations Detachments. A majority of the enlisted men selected for assignment to the 400th ASA SOD were from the top five percent of all U.S. Army enlisted soldiers. Also, each man had to pass a comprehensive personal security clearance investigation conducted by government agents prior to attending any of the classified ASA training programs.
The members were physically conditioned from preparing and completing the arduous airborne training and the physical testing required of all special operations units each year. The first Commanding Officer of the 400th ASA SOD (Abn) unit was 1LT Lewis "DEAN" Kirk. One of his first actions was to initiate a tough training program for the first two-dozen 400th SOD troops assigned to the new unit. He started with long forced marches with full rucksacks in the hot and muggy Okinawa spring and summer months up in the northern training area. The unit performed morning runs of up to three miles too. He encouraged his soldiers to participate in a variety of specialized training programs such as the following: the 1st Special Forces Group (Abn) SCUBA course; the Cold Weather and Ski Training Course up in Hokkaido, Japan; the Jump Master training course; the advanced HALO parachute course; difficult infiltration and extraction training from an USN submarine; extensive weapons training with a variety of American and foreign weapons; and serving as Cadre for the 1st SFGA Airborne Course on Okinawa.
Extensive participation in volunteer academic training was also encouraged for all of the enlisted troops. Some examples are cross training as Special Forces radio operations specialist; training in various foreign languages such as French and Vietnamese; enrollment in the Special Forces Qualification Training Program; and classified ASA extension courses (off-duty) were taken to enhance their professional military knowledge, skill
