Kill switch

There's a storm coming:

So the radio-controlled robots were retooled, for greater safety.   In the past, weak signals would keep the robots from getting orders for as much as eight seconds -- a significant lag during combat.  Now, the SWORDS won't act on a command, unless it's received right away.  A three-part arming process -- with both physical and electronic safeties -- is required before firing.   Most importantly, the machines now come with kill switches, in case there's any odd behavior.  "So now we can kill the unit if it goes crazy," Zecca says.

Thanks to Ray Kurzweil for the heads up.
