An army is only as effective as its mobility, so the Grand Army of the Republic was outfitted with an increasingly varied and versatile vehicle pool as the Clone Wars progressed. The BARC speeder gave a single clone trooper increased operational range, great speed, mobility, and firepower otherwise unavailable to the foot soldier. A more aggressive and bulkier design than slimmer speeder bikes used by the Jedi, the BARC speeder was used in scouting and escort missions on a variety of worlds. They were easily adaptable, with support struts that could be added to hold a stretcher or sidecar.
Clone Commander Neyo was stationed on Saleucami during the Outer Rim Sieges. While on speeder bike patrol with his Jedi general, Stass Allie, he received Order 66 directly from Supreme Chancellor Palpatine. The command identified Allie as an enemy of the Republic. Carrying out the order, he stopped his BARC speeder bike, falling in behind the Jedi. He and a wingman opened fire with their speeder-mounted laser cannons, killing Stass Allie and destroying her speeder bike.
A world of mixed terrain, from dank, swampy environments marked with strange bulbous plant-life, to arid deserts, Saleucami is an Outer Rim planet that remained untouched by the Clone Wars through most of the fighting. The settlers on Saleucami wished to avoid the destruction of warfare, and live out a simple existence at peace, only doing battle with the elements. Unfortunately, combat did come to Saleucami, and it was a major battle site during the Outer Rim Sieges of the Clone Wars.
A harsh rocky world less than a parsec away from Tatooine, Geonosis is a ringed planet beyond the borders of the Galactic Republic. Its uninviting surface is made up of harsh, rocky desert, and the creatures that evolved on Geonosis are well equipped to survive in the brutal environment. The most advanced lifeform are the Geonosians, sentient insectoids that inhabit towering spire-hives. The Geonosians maintain large factories for the production of droids and weapons for the Separatist cause in the Clone Wars. After the Clone Wars, the Empire chose Geonosis as the construction site of the first Death Star, restricting travel to the system and sterilizing the planet’s surface.
