The trooper was born in 32 BBY on the planet of Kamino. Following his graduation from basic training, he was assigned to The Muunilinst 10. In 22 BBY, when the rest of the Grand Army of the Republic was deployed, the trooper was present and in active service.
In 22 BBY, the trooper and his unit were deployed to Muunilinst, under the command of Jedi General Obi-Wan Kenobi and Jedi Commander Anakin Skywalker. While on deployment, the unit was assigned to sabotage a Separatist cannon located in the center of the city. En-route to the location, their gunship was shot down, resulting in the loss of their pilot. When evacuating the vehicle, the unit was ambushed, resulting in the loss of CT-43/002. Taking cover behind the fallen vehicle, Captain Fordo assigned this trooper and another to draw the droids fire off the main squad, to pinpoint their location better.
The trooper in charge of locating the droids immediately showed Fordo where their positions were at in the buildings, which Fordo immediately sent an ARC Trooper Lieutenant forward with a PLX-1 missile launcher and decimated the droids and the buildings they were in.
The Trooper and the rest of his brothers finished the battle and began to explore the city. While in doing so, they were met with resistance by a droid tank until an ARC Trooper Lieutenant destroyed the tank by jumping on top of it and firing repeatedly inside of it.
From there on the unit would make it to their main objective, the heavy turret and scale the wall to get towards it. The unit stormed the platform for the umpteenth time and eliminated all the droids. They then set charges and scaled up to a higher platform to avoid the fireball of what was once the heavy turret.
