Ah, okay, thanks.

Yep. It makes that buzz when it's running on its generator; it's silent when it's tethered. I wonder what kind of fuel it uses (probably diesel), and I wonder what kind of mileage it gets?

Thanks, Tsukiyumi.

I would guess that we'd have heard a deisel engine over the buzz; a gasoline one would probably translate to mileage somewhere around incredible, considering that the engine is only powering the generator, not an actual drive system like in an IC vehicle.

No, I think the buzz actually is the engine. Some sort of tiny cylinders running at a crazy high rpm. That's what my ears are telling me. Listen to the sound during the slow-motion parts; the buzz is clearly an engine of some sort.

I guess whatever fuel it uses would be the most common the military uses. I'll have to ask my buddy from the Corps.

That would be diesel. Every ground vehicle uses it in the US military, for commonality.

I think it is odd that they have the gas motor like that. It sounds like a medium sized hand tool motor (chainsaw, blower, etc). Would a motor and gas tank weigh less than a corresponding motor and battery pack? In weight to performance, which would last longer, a gas system or a battery system?

Electric motors are over 90% efficient but they are heavy as are the batteries. They're better off using an ICE until battery or fuel cell technology catches up, of course they could just use a tether. Some WWII German "robots" did that.

Check out its little cousin :-

"LittleDog," the pint-sized alternative to the BigDog

It reminds me of an AT-TE.

Now we just need some blasters and funny helmets, and we'll REALLY field a ground force to reckon with!

I bet the designers of these had a little fun reenacting TESB using those cute little spy planes - "Go for the legs!"

"Use your harpoon and tow cables!"

"Attack pattern Delta, go now!"

Wait till the invention of self toasting bread.
