[@Bartimaeus]: I didn't have exact measurements in mind, but in terms of kinetic weaponry it's all going to be pretty massive rounds for a lot of the weapons. They're scaled up to 20-meter on average mecha, after all.

As for the damage they can withstand, it varies in terms of how well-armored an individual AUG is. Mobile Armors are pretty much going to be fodder in most cases in comparison, though.
