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.
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.
A clever if flighty pit droid programmed in piloting, WAC-47 served as part of the 91st Recon Corps, reporting to Clone Commander Neyo. He was drafted into service as part of D-Squad, a special missions group of droids assigned by the Jedi Council to recover a vital Separatist encryption module. WAC-47 did not always see photoreceptor-to-eye with the mission's commander, Colonel Meebur Gascon, who treated the loyal droids as property. WAC-47, who seemingly had a program glitch that was unable to properly register the colonel's rank as anything other than "corporal," insisted Gascon treat D-Squad with the respect they deserved.
