The CT-5 batch was a batch of Clone troopers that was rather famous.
Captain Jag, born CT-55/11-9009, was the most famous of the batch. Jag was placed in charge of the 127th Gunship Wing, where he served in the First Battle of Geonosis as a Commander. He would survive the battle and go on to fight in the Battle of Katraasii. However, he would make a mistake during the battle, which forced the troopers to retreat.
He would be demoted and became a Captain. However, Jedi General Plo Koon witnessed Jag's skill and placed him in charge of flying the experimental ARC-170 starfighters. In 19 BBY, Koon, Jag and CT-57/11-9048 were all deployed to Cato Neimoidia, where Jag and CT-57/11-9048 received Order 66. They killed Koon, which caused the deaths of a Staging Area unit on the surface.
CT-5/501 was another trooper of the batch. He served in a Battle on Raxus Prime. The trooper and his brother CT-4/163 were stationed on the planet helping take count of civilians. The droids attacked them, killing most of their squad. The two troopers, alongside an orphan known as Teff, fought off the remaining droids. CT-5/501 was a pilot in a LAAT as well. The two escorted Teff onto their Republic cruiser, the Candaserii.
CT-5/373 was a clone trooper that was also apart of the CT-5 batch. The trooper served at the First Battle of Geonosis, where he flew in a LAAT and attacked the droids in the arena, where the Jedi were about to be executed. The troopers saved the Jedi, taking off from there. CT-5/373 would then continue to fight the battle and survived it.
