A Tacluchnatagamuntoron, also spelled Tac'unitagamunition and Takunitagaminituron or simply Tac/Tak for short, is a small Goa'uld device, rather similar in appearance to a Goa'uld shock grenade. It is remotely activated, and fires small bursts of energy at warm objects, such as warm-blooded beings and flares. (SG1: "Deadman Switch")
