Where Is The Navy Smiley??

Looking at the smilies available, I see Air Force airplane smiley, Army Person smiley, and Marine smiley. I don't see a boat or submarine with a smiley, or am I overlooking it? If there isn't one can a Navy Smiley be added? Thank you Captain MJ for looking into this very serious omission, especially before the most important football game of the year. :D
