"Hundreds of thousands of American servicemen and women are deployed across the world in the war on terror. By bringing hope to the oppressed, and delivering justice to the violent, they are making America more secure. "

It was a school run by a USARF (United States Army Reserve Force) unit from Ohio.  We called them the Ohio Woodpeckers (anybody want to guess why?). 

It was literally a school for "The 1st U.S. Army Area."  First Army was a "CONUSA" (Continental United States Army) subdivision, and included much of the United States east of the Mississippi.

The Reserve unit/school would mobilize for about eight weeks every summer. They took over a section of the WWII era white woden buildings located near - yes - the old stockade.  They taught a series of courses, from two weeks, up to two months, both skill training and MOS producing.  These included: "S2 Combat Operations"  "Security Manager"  "Tactical Intelligence Staff Officer MOS 35A"  "Order of Battle 98B"  "Prisoner of War Interrogation (base and refresher)"  "Language Refresher,"  etc.  The students were a mix of mostly USAR and NG soldiers, with an occassional AD student who could get a quota.

In the late 1970's I attended two of their two week courses: Security Manager and S2 Combat Operations, when I was assigned as the S2/S3 for my Special Forces Company (Company C 3/11 SFGA, the old T.O. & E., when a Special Forces Company had a staff).  The school was very well done, professional, and with motivated instructors.  I volunteered to come back as a faculty member, and was interviewed and selected as a guest instructor. I went back for several years and taught over the summer, making some good money while a young starving college/law student. 

So the possibility that he was a student there, as AT, ADT or ADSW is entirely likely. The photograph looks spot on for the location, together with the old style fatigues.

Well, I remember the Florida Army National Guard getting detailed to move a group of endangered woodpeckers from Ft. Stewart, GA down here to Camp Blanding, FL as part of a environmental relocation task order!  Could it be remotely related to something along those lines? Nah...way too farfetched!
