[StarWars] So what exactly happened to the droid army after episode 3?
gpt
It was automatically shut down on Palpatine's order in Revenge of the Sith. However some Droids didn't hear or obey the order, as seen in Rebels. The aforementioned Droid battalion remained active under the leadership of a Tactical Droid, and briefly fought Ezra, Kanan and Rex before joining them to fight off the Empire. They were invited to join the Rebellion, but calculated that the chance of victory against the Empire was extremely low. They then travelled elsewhere.
