Weak ship, fairly good weapon, dangerous in swarms and they always come in swarms. They will be led by either a Dwarg Master or a Dwarg Colony station, and if something (including the player ship, and wingmen and autons) destroys their leader, some of them will start following whatever destroyed it, with the message “WE foLLow thE stRong”.

If a swarm is following a Dwarg Master, they may come after you and attack, and if they drop your shields, the Dwarg Master can EMP you, leaving you to be pummeled by the raiders. Be careful.
