Under the Privacy Act, because it has your name on it, you're entitled to have a copy of it.
For me, I've only served as a medic on six medical bases. It's part of your routine that you do a stint on the surgery floor and you do a stint in medical records. As part of your duty, when someone is released, you stand at a photocopier...and yes, it's a stupid thing that you have a sergeant, who you're paying $75,000 a year, to stand at a photocopier and photocopy a medical file.
My personal medical file, in the file in the military, is three volumes. It takes up two bank boxes. It's sitting in my closet.
