Despite what some of the uninformed here are saying, these rats don’t fight solo, it’s typically a fleet of 5 ships that hunt players around the system, each one is a fully faction fit dps/tank spec equivalent of a player in a frigate. Those kestrels output IMMENSE dps for a npc, because your really fighting the equivalent of an actual player in that ship, (Who is 50/50 dps/tank fit.) five of them. They can break the tank of anything that mines, and a good number of combat ships without significant tank.
However they do not scram/web in the hunting parties, only escalation fleets for their haulers/miners scram/point.
