During the era of the Clone Wars, a specific clone trooper group operated under the command of both the Jedi General Eeth Koth and the Clone Captain Lock. The clone troopers belonging to this group wore Phase I clone trooper armor, distinguished by its green and yellow colored patterns. In the year 21 BBY, this group found themselves aboard the Venator-class Star Destroyer known as the Steadfast. At this time, they faced an assault launched by Supreme Commander General Grievous, who was on his Recusant-class Commerce Guild destroyer within the Saleucami system. Following his capture by Grievous, Jedi Master Koth instructed Captain Lock and the troopers under his command to leave the cruiser.
