Ernest has always dreamed of driving ARMY big rigs and armored vehicles. So, desperate to get behind the wheel, he lets his good buddy, Sgt. Ben Koski, talk him into joining the ARMY RESERVES. This leads to a series of comic misadventures as Ernest battles the brass and takes command of the ARMY's rolling stock. Although he'll never be a textbook soldier, Ernest uses his own comic brand of not-so-common sense and courage to take on the power hungry Middle East Dictator and his dreaded secret weapon. It's Ernest's biggest challenge ever as he goes all out to save his band of military misfits and a young boy orphaned by the war the he befriends along the way.
