I have read several stories about men being transferred from the US Army Air Corp to infantry and armor units.
The whole USAAF unit wasn't disbanded, they were given new T-O & E's, which made them appear to have excess personnel.
The men were then transferred to Theater 'RepoDepo's', and subsequently to combat arms units. Not to say AAA wasn't considred a combat arm.
"Infantry Division'" in the Shoshonean linguistic group means 'meat grinder').
Where'd you hear that?
