The Warden 10-24 security droid, also known as the Red Terror, represented a pioneering design in security droids produced by Ulban Arms. Although advertised as a gladiator droid, the company was aware that its primary purpose would be security. Originating in 4015 BBY during the era of the Old Sith Wars, these droids marked a significant advancement in the field. Instead of fingers, they had gun barrels, and their chest armor could be opened to expose some of the strongest laser cannons ever integrated into a droid the size of a Human. On Telti, an important moon where droids were manufactured, the "Red Terror" units served as the only security force. They were notorious for resisting memory alterations and could be extremely harsh in carrying out their security functions.
