A few months after the Dominion's founding, Alpha Squadron was dispatched to Char in order to "flush out" the zerg. Alpha Squadron was on the receiving end of the casualties however, a receiving end which included the zerg overrunning the science vesselAmerigo. In response, a demolition team, Jacobs included, was sent to investigate and, if any zerg were present, destroy it.
The marines had brought a high yield explosive with them, along with a number of beverages. While enjoying such a substance along with his teammates, Jacobs was suddenly impaled by a hydralisk's claw from behind, piercing his skull. Seconds later, his corpse was lifted up and away from his fellow teammates.
