Disruptor burst

A disruptor burst was a type of adjustable strength plasma discharge that could be fired from a Jem'Hadar plasma rifle or pistol. 

The disruptor bursts used on the Jem'Hadar weapons had three settings: a stun setting that caused unconsciousness, a lethal burst with anti-coagulants that were designed to slowly kill their enemies if the burst itself did not,  and a more powerful burst capable of vaporizing a humanoid size target.
