A tech stormtrooper, who was a human being, functioned within the First Order. This tech stormtrooper participated in the mission to Varkana in 34 ABY as a member of a stormtrooper group accompanying Commander Pyre and Agent Tierny, with the objective of locating Resistance operatives.
To force the BB-series astromech droid CB-23, who had been captured and belonged to the Resistance, to disclose the whereabouts of other Resistance members, they used electrocution. After the trooper had successfully accessed the droid's databank, Tierny instructed them to extract the information from the droid and subsequently eliminate her. Nevertheless, after Tierny's departure, CB-23 connected a cable to the tech stormtrooper's backpack, which resulted in the trooper being electrocuted and rendered unconscious.
