What does the bird emblem represent on this uniform?

That is called a ruptured duck. What you got when you finished your time during WWII .

(Ruptured duck) symbolized an GI discharged from service.

This is a WWII Honorable discharge pin.

I like the "turn-to-the-right" tale. An old timer once told me the position of the wings and body posture makes the bird look like he has just been kicked in the "eggs" (or words to that affect).

(Warrants all wore the same branch insignia regardless of specialty back before the aviators recreated the entire Warrant Corps in their own image. Since the "Eagle Rising" appears to have suffered the same abuse many of my fellow warrants also used the term "Ruptured Duck" to refer to the insignia.)

Thanks.

RUPTURED DUCK PIN! IT WAS ALSO THE NAME OF ONE OF THE B-25 BOMBERS THAT FLEW IN THE DOOLITTLE RAID! THE PILOT'S NAME WAS TED LAWSON

It's the 'Ruptured Duck.' WWII veterans wore it on their Class-As.

Formally called, the Honorable Service Lapel Patch. It was rewarded from Sept - Dec46. Originally was a pin made out of brass until the shortage of metal and then was made out of plastic or the patch.

Ruptured duck. Says the one wearing it was honorably discharged.
