"I wonder how strong it is. All its equipment looks very vulnerable to small arms fire. They would have to armor it up, and then it would have to be strong enough to move with the weight of the armor. Enemy combatants would have to switch to higher calibers and/or armor piercing rounds.

The key advantage will be that no human life is at risk. A second advantage is if it can carry more armor than a human, then it can carry out missions where a human would be shot and stopped.

I wonder how much it would weigh with heavy armor and sufficiently powerful motors to move the armor. it would make sense that it might be bigger, too.

And it needs some independent mobile power source. A small electric generator as a backpack might be able to generate enough power to fulfill the endoskeleton's requirements. Or a battery, for shorter operations. How about putting a larger generator on a Big Dog and having the two move forward together? The connecting power cable would be like a leash. lol"
