Jacobs

"Yeah, I got your Zerg right here..."

- Jacobs moments before being impaled by a Zerg.

Jacobs was a Marine in service to the Terran Dominion.

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 recieving end of the casualties however, a recieving end which included the Zerg overunning the Science Vessel Amerigo. 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 Zerg's tail from behind, piercing his skull. Seconds later, his corpse was lifted up and away from his fellow teammates.

It appears that Jacobs possessed an O blood type.

Trivia
It appears that Jacobs was 'salvaged' from the StarCraft Beta, as both versions are identifiable by names painted on their armor.
