Now where's the robot that picks up the busted robot that went to pick up the soldier?
And why did they choose a bear? Why not a kitty? I would much rather have a cute cudly kitten-bot resuce me out of the sandbox than some ferocious bear.
Back to real life now, could it be maintained easily with a good chance that it won't malfunction or break down? Now, say it can only take a few 7.62 russians/soviets before it gives out, whats the point? Being they're robots they wouldn't be amassed, and if a unit had one, they would probably only have one, or spare parts. Eh IDK
In the end, i think the brass would look at it like this. How much does it cost to train a soldier, and manufacture one of these. If it takes two men dieing to save one soldier, will that cost less than one of these robots doing the same?
