Army Strong Prom Dress?

I have my prom dress, but I want to wear something with it that represents our troops. I'm graduating in a week and I've joined the army. I don't have any pendants or anything, but is there maybe like a specific color ribbon (like they have pink for breast cancer) that I can maybe sew on to my heel? My dress has straps that criss cross and tie at my lower back too, so I could put something on the bow, but I want it small and suddle. Or anything I can make at home to represent our troops? PS my dress is long & red.
