I did nto want to put this in the other forums but can anyone tell me what an Officers 66-1 for was and what information it contained? Also, I am trying to find what "S-1 equipment" may be refering to.
Thanks!
Brian
That's okay, but I moved this to the Research section, since it refers to abbreviations related to same... 
Here's what the "S" designations refer to:
S-1 Adjutant
S-2 Intelligence
S-3 Operations
S-4 Supply
S-1 Was the Personnel Section of regimental or battalion headquarters. So S-1 equipment would refer to anything related to that specific office.
More to come...

WD AGO Forms 66-1 and 66-2 refer to officer qualification cards.
An interesting tidbit for you and our readers. Contains a few examples, but they are small and difficult to read. Trying to find larger images, so you can get a better idea.
