Need help identifying old military uniform
 

I found this old uniform while going thru my dad's belongings after he passed. He was in the Air Force and Navy in the 1940s. Can anyone advise if this wool uniform could be a uniform from one of these services? Any help would be appreciated.

U.S. Army 4th Armored Division Brigade Tank patch. Staff sergeant rank.

Thank you!

you can put the pictures in copolit (AI) and it will tell you about them.

The USAF was not established as a separate branch of service until 1947. Prior to that it was part of the Army!
