Here's the official description from the site:
Dan "D2" Daniels, an old broken retired NCO. One foot nearly in the grave with past memories of a noble America. Dan takes up the mission to restore his beloved America to a the land of hope and freedom, while trying to save the world from alien invaders. Dan assembles an Army of elderly veterans armed with the technology from a crashed alien space ship and its absent minded pacifist artificial intelligence to assist them in their mission.
