Rahm Kota

Jedi Master Rahm Kota was a wise Jedi of the Jedi Order during the Clone Wars. During the war, while most Jedi worked with their own clone battalions, working together to end the war, Master Kota did not trust the clone troopers, seeing them as unfit for battle and being untrustworthy. Because of this, Kota would form his own Group of Republic Mercenaries know as "Kota's Militia." This group was made of up of many warriors, such as rescued military prisoners, or skilled mercs who agreed with Kota's Cause. 
Kota's Milita would be his saving grace, as when Chancellor Palpatine issued Clone Order 66, Kota was able to avoid being killed during it's initiation. Him and his men would then go into hiding with a Republic Venator Class Star Destroyer of their own, re appearing during the Birth of the Rebellion era
