Read your answer to another's question and was hoping you could shed some light on this. Trying to learn the meaning of this (October 1944) World War II address. "3502 B.U.A.A.F. (T.S.), Section H. Barracks 189, Chanute Field, Illinois." Is this too basic to find out what type of unit, etc.? The best answer I've received, so far, was that "3502" may indicate it was a helicopter training school. Would greatly appreciate any help you could give. Thank you.
