A comparison depicts the Class 1 defense unit relative to the size of a Human male.
Class I Defense Droids, conceptualized by Imperial Captain Kist and manufactured by Ulban Arms, were intended to bolster the ground-based military forces of the Galactic Empire. This initiative may have stemmed from observations made during the Clone Wars regarding the effectiveness of droid armies. Nevertheless, the Empire dismissed the concept, and the Class 1 defense unit designs later surfaced within the Corporate Sector. The Espos employed them extensively, integrating them into their armies to suppress the Trianii, a tactic reminiscent of the methods employed by the former Trade Federation.
These quadripedal droids were equipped with a pair of medium blasters: a standard model and an anti-vehicle variant.
