The three different uniforms for Army personnel are the Army Combat Uniform (ACU), the Army Service Uniform (ASU), and the Army Dress Blues. Navy personnel have the Navy Working Uniform (NWU), the Navy Service Uniform (NSU), and the Navy Dress Blues. Air Force personnel have the Airman Battle Uniform (ABU), the Service Dress Uniform (SDU), and the Mess Dress Uniform. Each uniform is designed for specific occasions and duties within each branch of the military.
You use a ribbon bar. These are thin frames of metal or plastic with pins. You slide the ribbons onto the frame work in the correct order and it pins onto the uniform with the standard sort of pin with cover. Ribbon bars come in metal for a specific number of ribbons, or you can get plastic ones that can be clipped to size. For a couple of ribbons, I prefer the metal frame, but once you get over a couple of rows, the plastic will provide some give and movement with the body.

Navy Cross is the Navy's equivalent to the Army's Distinguished Service Cross and the Air Force Cross. It is usually only awarded to Navy, Marine Corps or Coast Guard personel, but can be awarded to any member of the US Military. It is the second highest award for valor a serviceman can receive. Essentially its a step down from the Congressional Medal of Honor. Note: Not really a big deal, but it is referred to as a medal, not a ribbon.
