Do you have any additional information. It really depends on branch of service, and really what you are trying to prove. Give you an example my father spent 28 years in the Army Reserves and was never issued the Army Reserve Gorces Medal.
Long story short I had obtain his pay stubs from DFAS and Annual points statement. Then submitted paperwork to the Army Awards and Decorations Branch for approval. Then they submitted orders and sent medal. Also had them correct his discharge to reject unit war credit for amphibious assult landings.
So it really depends on what branch, many have their own way dealings, and you may need to show burden of the proof.
For army you cannot Reccomend yourself
You need to find someone in direct contact or knowledge of such events. I've heard of some veterans using Congressional help in getting recommendations approved.
