Hmmmm .... so I guess I would deliver my tank to the battlefield, then drive
home and battle remotely, then drive back and pick up my tank ?

So, with all this "Mad Scientist" talk, it would seem that a true remote
battle is even closer to happening. Imagine a battlefield that none of the
tankers have seen. The only images available are what each tank can
produce, one gunsight, one wide angle. Hits are registered by on-site
scorekeepers...... Wow.
