Much of the military of the holdout were droid assets from the previous Confederacy of Independent Systems. A droid battalion comprised of at least twenty B1-series battle droids, several BX-series droid commandos, several droidekas, an air strike team, an OOM command battle droid, a Armored Assault Tank Mk I reprogrammed to protect Desix from hostile Imperial takeover. They were led by a T-series tactical droid reporting directly to Governor Tawni Ames.
During the mission to Desix, these forces were split into one squad that protected the outskirts of Desix City at a bridge, an air strike team located at the walls of the city, several squads patrolling inside the city and a squad made up of only commando droids located inside the bell tower, where Ames and the T-series tactical droid were located.
When an Imperial Nu-class attack/transport shuttle arrived at the planet, Ames ordered the Tactical Droid to open fire on the shuttle. The Tactical Droid complied and ordered the old Separatist Tank and the Air Strike Team to fire on the shuttle leading to the shuttle crashing at Sector Five in the farmlands. When the shuttle crashed, Ames then ordered the Tactical Droid to send scouts to the wreckage and check for survivors.
When scouts in the form of five B1 Battle Droids were sent to the wreckage, they found no survivors and contacted the Tactical Droid. The Tactical Droid then ordered the B1 Battle Droids to head back to the fortified city. However, just before the battle droids were about to leave, what remained of Crosshair and Cody's team opened fire at the B1 Battle Droids thereby giving the squad some time.
The squad then traversed the terrain and arrived at a bridge connecting a city to the Farmlands. While the squad was discussing how to enter the city, CT-9904 suggested that he will draw the tanks fire while the rest of the squad advances to the Main Gate. Cody, after some convincing, agreed and Crosshair used his 773 Firepuncher rifle to purposefully miss hitting the droids operating a tank. This caused the tank to re-position towards Crosshairs position allowing him to fire a shot at the barrel of the tank thereby causing the tank to explode. With the tank destroyed, Cody and his men advanced towards the main gate while Crosshair provided covering fire. With the dessix droid air strike team dealt with, Cody and some clone troopers rappelled to the top of the main gate and opened the gate allowing the rest of Cody's squad including Crosshair to enter into the city.
After entering the city, Cody split his forces with Team two taking the south part of the city while Cody, Crosshair, Nova and Wyler took the North part of the city. This led to the Tactical Droid ordering his forces to execute Protocol 4.
After some close quarter combat in the city with Wyler dying to the droids, North Team managed to reach the city square where they then infiltrated the Bell Tower. There, the troopers were caught by surprise with BX series commando droids ambushing them leading to Nova dying. To escape the ambush, Crosshair and Cody were pinned down by the commando droids at the staircase of the Bell Tower however managed to defeat many of the BX- series commando droids. During this battle, Crosshair was injured but convinced Cody that he could make the shot. Trusting Crosshair, Cody threw a puck as far as he could towards the Tactical Droid allowing Cody to kill 2 Commando Droids and the tactical droid in one shot.
When reaching the Upper Floor of the Bell Tower, they confronted Governor Tawni Ames with a blaster at Governor Grotton's head. With some persuasion however, Ames let Grotton go. Immediately after being released, Grotton ordered Cody to kill her. Cody promising Ames a peaceful resolution between Ame's people and the Empire prior to Grottons order, Cody was unable to kill her leading to Crosshair to instead kill her. After Ames death, Grotton ordered the 2 clones to hang her body at the City square.
Ames death led to the dissolution of the Desix Separatist Holdout and the Imperial occupation of the planet. Distraught over what had transpired, Cody left with Crosshair and few clone troopers in a shuttle to the planet Coruscant where he went AWOL.
