NFL Sunday Ticket Stream Only - DirecTV

I am a member of the United States Army, currently stationed at Fort Carson, CO. I live in the barracks with about 300 other personnel. I am not allowed to have a satellite dish installed at the barracks. I am in the same situation as a college student who lives in the dorms. I am wondering if there is a way that I can access the stream only option to be able to watch NFL games without having to go to a sports bar.

This question, "NFL Sunday Ticket Stream Only," is about DirecTV channels, programming, equipment, and sports.
