ARC-1001

ARC-1001 or 'Jacko' was an Advanced Recon Commando Corporal. Jacko trained in the ARC trooper ways as soon as he finished his regualr training. Jacko had the potential to go higher in the ranks. Jacko was sent to Golden Squad after his ARC Trooper training finished.

Training
During his training on Kamino, Jacko had a chat to Jango Fett who told him that he was going to train him to be an ARC Trooper after he finished his regular training. Jango and Jacko became friends after awhile. As soon as Jacko finished his training he broke away from his friendship with Fett and continued his ARC Trooper training.
