The popular Discovery series “Dual Survival” has revealed to FOX411 exclusively its new military survival star: Joseph Teti.

Teti is a former Force Recon Marine, Army Special Forces “Green Beret” and a former operative in one of the most top-secret government counter- terrorist units in the world.

He joins professional survival instructor Cody Lundin – who hasn’t worn shoes for over 20 years – who returns to the Discovery show for his third season.

“There is no question, Cody Lundin is one of the world’s foremost experts in self-reliance and living off the land. And Joe Teti’s ability to survive a decade of combat in some of the most dangerous situations and harshest terrain on the planet makes him the perfect addition to ‘Dual Survival,’” executive producer French Horwitz told FOX411. “The differences between these two men couldn’t be more drastic, but each is formidable in his own way. This will unquestionably be the best season yet.”

In each episode of “Dual Survival,” the duo, equipped with minimal gear, is dropped into a stressful, death-inducing conundrum. The season opener, a one-hour special entitled “Unbraided” airing Jan. 1, 2013, features never-before season footage of Lundin, who introduces audiences to his new cohort, and gives fans a glimpse into what to expect from the pair.

The premiere is followed by “Mars on Earth,” which takes the two to the driest place on earth. Chile’s Atacama desert, which NASA uses as a testing ground for its Martian rovers.
