If only. [Yuan sighs.] We don't have batteries that could store that much power - at least, not in any form small enough to be portable. It's theoretically possible for a Rheiard engine to be powered off one, but with our current levels of expertise, it would be too heavy to lift itself. I've had engineers working on that for a while, along with mounted weapon systems - or rather, I did - but they never managed anything that would be practical in the field.
