BCA-11/X lightsaber practice droid, also known as BCA-11/X training droid, was a droid model produced by Baktoid Combat Automata before the Battle of Naboo as a training droid for the Jedi Order. The cortosis matrix in the bonding of the droid's quadranium armor allowed it to resist the lightsaber and made it harder to destroy. The droids were equipped with blaster carbines.
