Jaq Delor was a Mengsk Family security guard.
In 2478, a "corporate death squad" invaded the Mengsk Summer Villa. Delor guarded the Mengsks and their guests to the refuge, providing covering fire with his C-14 rifle. However, although he managed to take down at least two attackers, their gunfire eventually caught him in the chest, killing him within seconds.
