IG lancer combat droids, also known as IG-series battle droids or simply IG lancer droids, were a type of battle droid used by the Confederacy of Independent Systems during the Clone Wars.
These droids were created to resemble their Muun creators. They were also more advanced than the standard Baktoid B1 battle droids used by the Trade Federation. They were armed with giant energy lances and anti-vehicle mines and rode into battle on swoop bikes.
They were developed by Phlut Design Systems, a Muunilinst and InterGalactic Banking Clan-based weapons development firm. When PDS was unable to repay the IBC, the IBC responded by seizing the assets of the company and adding the battle droids to the military forces of the Confederacy of Independent Systems. As an InterGalactic Banking Clan asset, the new droids were renamed the IG-series.
IG lancer droids were led by Durge at the Battle of Muunilinst. They proved a match to Jedi General Kenobi's lancer troopers and destroyed nearly all the Republic's artillery during the battle. Some were also deployed during the Battle of Amaltanna, but were mostly destroyed.
