In the video, Rettig, who is on the left, can be seen shaking as both men hold up their right hands and recite words that sound like they are part of a swearing-in ceremony.
They then free-fall on the park's Terror-Dactyl ride down 150 feet into a canyon below.
After the ride, Rettig can be heard saying, "That was awesome!"
Sources say both men serve in the 4th Combat Aviation Brigade, 4th Infantry Division at Fort Carson. Laybourne is from Salt Lake City and Rettig is from Norman, Oklahoma.
