Not sure where in game you can see them, but can't you see them in the service record section of the site?
I am able to see my Top Medals and Commendations and they both have a "view all" button.
For some reason not all of my medals are there. For example, I have gotten many, many Rail Gun kills but my records say I have only two. Also, I have gotten many kills with the Plasma Caster and my records say I have none. Makes no sense. You can look at my warzone boss take downs and see that I've killed the Warden many times over; but if you look at my medals, I do not have the Warden Takedown medal, although I remember seeing it after it bested him.
