The disruptor bursts used on the Jem'Hadar weapons had three settings: a stun setting that caused unconsciousness, (DS9: "The Search, Part I") a lethal burst with anti-coagulants that were designed to slowly kill their enemies if the burst itself did not, (DS9: "The Ship", "Change of Heart") and a more powerful burst capable of vaporizing a humanoid size target. (DS9: "By Inferno's Light")
