Cry havoc and let slip the robots of war!

Some scientist/engineer, in a moment of frustration, must have pouted to himself that "it'd be so much easier to make robots that walked like animals than ones that walk upright like Man."
Then that enterprising soul formed a company called Boston Dynamics, got oodles of money from the Pentagon via their Defense Advances Research Projects Agency (DARPA), and started developing.
Now Boston Dynamics has finished several surreal robot prototypes that mimic quadrupeds.

The videos are short and worth a watch.
"BigDog"
"LittleDog"
Creepy climbing monster that weirds me out.
Alligator thing

Anyway, as far as "BigDog" is concerned, it doesn't seem that far off in the future that these things might become the faithful companions of soldiers, as dogs became the faithful service companions of humans thousands of years ago. Is it so hard to see a future where a group of soldiers has their packdog carrying a couple hundred pounds of dangerous ordinance? Is it hard to imagine a soldier, trapped behind enemy lines, activating his GPS device and LittleDog, with a gallon of water and two MRE's strapped to its back, sneaking through the forest to the trapped man?

All we need is a robotic dragonfly to swoop in and take video footage of the enemy.
