A flare gun is a piece of terran technology used for emergency situations, in order to send a flare up to a high altitude to signal for rescue. In emergencies it can be used as a makeshift weapon. Its function is similar to that of flare guns from old Earth, and the basic concept carried its way over to the Terran Confederacy and Terran Dominion. Confederate science teams that explored regions considered to be dangerous, such as Perdition's Crossing on Mar Sara, would carry one with them.[1]
