Doom's unit
Doom", a Clone Commander, commanded a squad of clone troopers in conjunction with Jedi Generals Tiplar and Tiplee. They made use of a unique version of the M3 Bulwark Blast Shields. Furthermore, soldiers within this squad were armed with Z-6 rotary blaster cannons in addition to Electro Magnetic Pulse grenades.
History

During 19 BBY, the Republic engaged the Separatists in combat on the space station orbiting the planet Ringo Vinda. The squad, under the leadership of Jedi Generals Tiplar, Tiplee and Clone Commander Doom, advanced and fought alongside the 501st Legion. The battle resulted in significant losses for the unit. In an attempt to break the stalemate, the Republic launched a daring offensive against the Separatists, successfully reaching the communications center.
While there, they formulated a plan to capture the Separatist command center. ARC trooper CT-5555, known as "Fives," and CT-5385, known as "Tup," received orders to gather ten men to reinforce Doom's unit during their advance. However, as Republic forces entered the command center, Tup entered a trance and, before anyone could react, fatally shot Tiplar.
Following Tiplar's demise, the clone troopers lost their offensive advantage, and droid reinforcements arrived. Jedi Knight Anakin Skywalker issued an order to retreat as Tup was taken into custody and escorted away.
