If they're anything as good as I hear, they can practically win the war themselves.

Soon after the Kaminoans began developing the Galactic Republic's secret clone army on their homeworld of Kamino, a special forces unit was conceived as a necessary addition to the overall operational effectiveness of the new military force. Jango Fett, a Mandalorian bounty hunter and the genetic template for the entire clone army, was confident that progeny would be engineered into the best soldiers in the galaxy, but also knew that there were situations that regular infantry was not suited for. As a result, he requested for a special batch of clones that he would personally train as Advanced Recon Commandos. The Kaminoans reluctantly agreed, but due to their disappointment in the failed prototypes, they felt little confidence that the second generation of ARC troopers would meet their expectations. Thus, they compromised with Fett; the bounty hunter would be allowed to train his ARC troopers while the Kaminoans proceeded with their plan to create the clone commandos, otherwise known as Republic commandos.
