Class A and Ribbon Help

The NDSM and GWOT can be worn just for service right now.

As for the Army service ribbon, you should be able to wear it after 4 months of honorable service because your medical degree could be considered a 'civilian acquired skill'. Could be wrong though, but they should be ok.
