This is a spin-off of "Fight Science" that's airing on Spike. The basic idea is that they test the different weapons that a historical warrior would use, input the results into a computer program & then run it to see who would win more fights out of 1,000. In the first episode "Apache vs. Gladiator", they brought in Chuck Liddell to help test out some gladiator weapons. Here's a link to where I've uploaded the video:
Chuck's portion starts at about the 10min mark.
