Despite his looks, Dennis is no Spartan, or an ODST, he is a Hazardous Materials Disposal Troop. He was born on Earth, in Austria, just before the Austrian-German War, which left little than a few Aryan Germans left. The Aryan Germans were the best soldiers the Galactic Human Alliance had, and at their fall, they strove to hire every last one of them. Dennis knew not of what happened, for he was only a kid. But from what The Alliance told him, there were little over one hundred Germans left. After that, he served with the HMDU, fighting many battles, including Primus VI and Polis VIII.
