MDARS

The new sentries at the United States' Nevada National Security Site.

I'm sure it's a leap forward, but where's the rocket launcher?  The electric Gatling gun?  Not even a Dalek-modelled voice synthesiser to bark out "Do not move! Do not move!" as the robot shines the pain ray on an intruder?  What?  No pain ray?  Good grief.

How disappointing.
