Do you have your elves build you that ordnance you arm yourself with? Do they have skills in building munitions as well as toys?

Or do you have a contract with a top munitions company like Raytheon or General Electric? If so, how do you afford that ordnance? Do you loan out the services of your flying reindeer to various world governments to conduct mercenary spy missions on each other to finance the purchase of that ordnance?

But WTF, Santa, why do you need munitions at all if you can simply bend space and time to project yourself far ahead of any pursuing jet or missile?
