Little is known about the origins of the stormtroopers, except that they were cloned in the orphan factories of Kamino by the Kaminonannians to serve as the Grand Army of the Republic. Wait, that's more than a little. In fact, there's more.... Because they all looked the same, clone troopers would use facial tattooing and ritual scarification to individuate themselves from one another. Okay, I was completely wrong - a fair amount is known about stormtroopers.
