Enforcer A01 was basic humanoid-shaped droid design which was used as a template for production of various droid models - both for military and civilian purposes - by different droid manufacturers. Full production ID for this design was droid.assassin_droid.enforcer_a01. Like most humanoid-shaped models, it allowed to install wide array of the internal weapons and protective shileds, to complement its abilitiy to use most blasters, rifles and melee weapons.
The design was often used by the Empire as a template for both military and labor droids.
