Comments: SIGMA 6 is the code name for a new group of covert GI JOE operatives with highly specialized capabilities. They use innovative technology and gear designed exclusively for each of their missions. Working against them is the evil COBRA organization whose goal is to take control of the world by sabotage, espionage and outright destruction. SIGMA 6 fights them at every turn and provides a swift solution to critical situations around the globe.DUKE is highly experienced in the unique challenges of sub-zero conditions from his missions in the Siberian tundra and Antarctic biomes. This made him the optimal choice for a mission to disable a COBRA base hidden in the Arctic. He traveled from the rendezvous site on thruster-powered skis that provided speed and maneuverability, both of which he needed when he suddenly encountered a COBRA B.A.T. patrol. During the ensuing chase, the robots forced DUKE to leap into a deep crevasse, but the resourceful commander used his grapple pick to stop his fall and climb out of the treacherous void. He secretly followed the robots back to the base and decommissioned the building with a blast from his dual-missile launcher.
