@Pisarz I'd say, the first comparision was actually way more accurate, as we don't really know how big those machines are. I mean, I'd say a Scout is the size of a car, but I'm not really sure because it was never mentioned how big they were.

Well, they were modified industrial robots, so maybe this scale could be used:

I don't know what to say about the second one, though, discounting this: that human is too big for me.

Ok. Got it.

By the way, the "broadsword-like" arms would be its legs, but also, I thought about putting some hidden retractile blades in them, for close combat:
