A specialist in guerrilla engagements and had been posted in both Da Nang and Cambodia during and after the Vietnam War, alongside Al Dillon.
After discovering that their mission was a set-up to dupe them into eliminating the rebels in the area, Dutch's squad came into contact with a Predator that stalked and killed the elite soldiers one-by-one. Dutch was one of only two survivors, the other being guerrilla member Anna Gonsalves. He was subsequently interrogated by the Other World Lifeform Taskforce regarding the incident, but he later escaped from their custody and disappeared.
Dutch is named after and roughly based on Arnold Schwarzenegger's character in the original Predator film. His bio states:
"A cyborg created to fight extra-terrestrials. He lost his arm in the 2nd Alien War, and has since had it replaced with a smartgun rig. He lives only to avenge himself against the aliens."
