For some reason I cannot seem to post a picture here but it's a shoulder patch. Top half is white and lower half is red. To be honest it looks like a Polish flag with a big black A in front of it. Any help identifying would be nice.
Hello there! As your question is related to looking for identification/information regarding military personnel, our Guide on Military Identification may be of use to you.

Sounds like the First Army insignia, after 1950.
