Metal Storm's Talon UGV grenade launcher

As if we didn't already have enough armed-and-dangerous
military attack drones, the Army's latest is the Metal Storm-built Talon UGV (unmanned ground vehicle), which fires freaking huge 40mm grenades—potentially up to 48 of them. Yes, that's a whole lot of destruction,
and no, we won't be particularly excited by the machine until we can break up neighbors' parties and midtown rush-hour traffic by sending one in.
