Yes, I'm very aware that the SGC bunch are technically not soldiers. My goal with this video, though, was to incorporate Stargate into a... larger context. It's not the best thing I've ever done, but I'm reasonably happy with it, and I think I did what I set out to do.
Please let me know what you think!
