DD 214 War Campaign Question

Quick question - and I hope I word this correctly and don’t cause confusion.

My Intel unit was part of OIF and OEF . We worked many MANY missions for both campaigns. I know at some point , while still active duty, our unit was awarded medals for both war campaigns.

How do I verify this information to know my DD 214 is up to date ? I have been out since 2014 and this is an early morning/late night can’t sleep thought. I have nothing on my papers to verify OIF / OEF.

Does anyone know how I can get a copy of our unit being awarded these medals and how to update my person records ?

Thanks so much!
