LR-57 Combat/Retail Droid
The LR-57 combat droid, also known as the Retail Caucus droid, retail droid, or mine droid, was a model of battle droid used by the Confederacy of Independent Systems during the Clone Wars. Primarily used as sentinels, these droids were bipedal and possessed two upper limbs terminating in two blaster cannons, four in all.
