My dad was a doctor during WWII, and enlisted in the US Army. After my dad passed away, my mother ordered a flat bronze marker from The Department of Veterans Affairs (VA). She filled out the application correctly, but when it was sent to her it had the wrong information on it. My dad was in the Army, but they sent a marker with the US Marine Corps inscription! After a lot of red tape and correspondence back and forth, she finally received the correct marker. I don't recall what she did with the Marine Corps marker.
