Believe it or not, some celebrities have done some time in the service.

We have seen plenty of actors and actresses portray soldiers in films, but it might be difficult to imagine them actually serving. When we watch our favorite artists on stage, it's sometimes hard to picture them in a military uniform.

However, some of them have made the sacrifice to serve our country.
