This photo was taken at the US Army OCS graduation formal dance at Fort Benning about 5 years ago. As the candidates have not been commissioned yet, they wear blank shoulder boards and "OCS" rather than "US" brass in their upper lapels.
There is something about the uniform of one soldier that you seldom see. What is it?
The second guy from right is wearing his branch insignia which is the Adjutant General Corp into which he was commissioned not long after this picture was taken. The guy on the left is Engineers, the next Armor, the guy you mentioned AGC, and the right hand guy is Military Intelligence.
