The Immobilizer pulse was a weapon attached to the Pantak-class Vigilante. As the Pantak-class Vigilante was a pursuit vessel the immobilizer pulse was designed to disable and not destroy a vessel. It was used on the Peacekeeper/Leviathan hybrid ship Talyn as part of an attempt to recapture it and its captain Bialar Crais. The attack left Talyn very damaged and Crais unconscious from its pain feedback. ("Thanks for Sharing")
