A somewhat timid astromech droid that served with Jedi Thongla Jur during the Clone Wars, U9-C4 was called upon to serve the Republic as part of D-Squad, an all-droid special missions unit led by the gruff Colonel Meebur Gascon. To carry out the vital assignment of capturing a Separatist encryption module, Ceefor was outfitted with an intense laser cutter capable of slicing through most materials. To fire the laser, Ceefor had to anchor itself firmly since the modification packed quite the recoil.
Colonel Gascon was the no-nonsense commander of D-Squad's inaugural mission. His tendency to dismiss the droids as inherently inferior operatives did not enamor him to those under his command.
The sole non-astromech droid of D-Squad, WAC-47 was a smart-mouthed pit droid assigned to pilot the insertion and escape shuttle to the Separatist fleet.
A fellow member of D-Squad, R2-D2 was modified for this mission with enhanced booster rockets that enabled him to reach the heights of the cryo-chamber that contained the mission objective.
A pink hued astromech droid, QT-KT was outfitted with a specialized magnetic coil vital for carrying out D-Squad's mission.
The last member of D-Squad was M5-BZ, a modified astromech droid with a hollowed out cranium that housed Colonel Gascon's command module.
