Talk:Battle of Ryloth (Galactic Civil War)

I have a question....if this was an early battle of the Galactic Civil War, how could the Viper-series probe droids be used? The Viper-series wasn't developed until around the end of A New Hope, as revealed in IG-88's story in Tales of the Bounty hunters. They were created specifically to search for Luke...and to act as IG-88's "eyes" around the galaxy.
