Spooky. Not too hard to imagine it with a gun.
And I'm sure you're not the first to do so. I think many hard-ons around Pentagon has been inspired thoughts of what such a thing with a machine gun could "accomplish" in many a defenceless hot village around the world. Napalm has gotten so expensive.
And until they can think well enough for themselves, just plug them remotely into videogames globally, and let the kids do some "defending their country" while they think they are playing.
