Avengers of Tantura

When the Hunal fleet lands on the world of Tantura in search for their own world's depleted metals and minerals, they receive quite a surprise as the supposedly docile inhabitants fight them literally to death when they try to turn them into slaves to extract the abundant mineral deposits.
Once the Tanturans overcome their brutal lizard-like opressors, and sure that their enemy will return to avenge the lost fleet, they recruit ten retired American generals who are famous for their military expertise for the purpose of teaching them the art of war, eastablish a superior military force, then lead them to battle.
Thus begins the saga of the Avengers of Tantura!
