1. Apology, I just saw this message today 8 July 2008. I hope this reaches you.
2. National Archives and Records Admin (NARA) keeps many histories of units never published. These histories would have been written by the commanders or designees. I found my father's unit, the 762nd AAA Gun Bn, and the 891st AAA Gun Bn.
3. NARA is divided into several regional archives. Those AAA battalions that served in Panama are kept in NARA College Park, Maryland.
4. Although you are asking about the roster, this history does not have a roster per se. But any letters, orders reassigning personnel do name those soldiers affected by said letter, order etc. The histories I have included photos taken near the time of discharge. Individual photos in case of the officers and a short bio. Group photos in case of the enlisted by battery. Photos of the history of the 762nd do not include enlisted names. Photos of the history of the 891st do have enlisted namers.
