Suhiir,
a few years from now you may be thinking about adding 'BigDog' ammo carriers to your USMC OOB. I understand the Corps has been testing them as well as the U.S. Army.
It creeps me out when I see it moving.
I suppose it won't stampede under a mortar barrage. But that only goes to show that it is less intelligent than a donkey or mule.
