Photon Storm was a team comprised of Ed Hoppitt of Storm 2, Andrew Marchant of Tornado and Alan Young of Cronic/Robots live. If you were trying to assemble a dream team of robot builders that would be a pretty good combination. Given Alan and Ed's connections I would reckon they got the Armox direct from SSAB.

I'd also bet that Minotaur drum packs far more energy than a 50cal round; which is probably what Armox is designed to stop along with other small arms fire, and is probably going to be in contact with an opponent for longer, imparting more energy into what it hits. I'd link you a video of the fight but it seems ABC haven't got it up on Youtube which is weird.
