Clone troopers were identical soldiers created by the Kaminoans to fight in the Clone Wars. serving under Jedi leaders and other Republic naval officers on different worlds and other planets from the Tingel Arm to the Mid Rim, these soldiers were the predecessor of the Stormtrooper, but would still see active service when the Galactic Empire rose to power in some cases however, the Clones would refuse Order 66, and fight on with their Jedi generalsNathaniel Kenobi, Obi-Wan Kenobi, along with other notable Jedi, fought with them in the Clone Wars and after, when he saved them from the Empire.
When the Clone Wars erupted after the events of the Battle of Geonosis, the Clones were employed all over the galaxy to crush any Sepatarist strongholds, seeing action all over the galaxy, many however died in the ensueing conflicts, and were in short supply during the Clone Wars, but there skills outmatched that of the Battle Droids used in the Confederacy of Independent systems arsenal.
the Clones were assigned DC-15 blasters, and a few other DC Weapon variants, though many clones complained of its low fire weight, and inaccuracy, an all most definite nod to the later Stormtroopers, however, there were other Weapons and Survival gear available to them in the field, being training in grappleing techniques and jetpack combat.
The clones were deployed over the entire galaxy to quell the Sepatarists, however, they were placed in specific classes also, Pilot, Commander, Captain, Officer, and on occasion, General in the field.
