The SB-71 is used by many organizations, from Prague police to the Dvali crime family as a way to patrol areas and, when necessary, to take out targets. It has a turret located slightly to the left of its center frame, near its camera.
It is most likely the precursor to the Page Bravo-3 Peacebringer considering it is the first bot to move around on two legs.
Like other bots, the SB-71 is susceptible to EMP attacks and remote hacking. However, unlike drones, most times there is a security terminal somewhere on the premises that can control them, effectively turning them off or used to clear out enemies.
