Skippy had explained that Guardians were small machines designed to protect fixed assets like a star system. While Sentinels relied on sheer size and power to accomplish their assigned missions, Guardians had to swarm to utilize their full capabilities. By ‘small’, I mean a typical Guardian was the size of a dropship, although they could be as small as a toaster or larger than a starship, depending on their role. Also unlike a Sentinel, Guardians could make decisions on their own, without direction from a master AI like Skippy.
