[@Havoccultist] Maaaybe scale down the numbers a notch, but otherwise, I'm good with it. :)

Cool. I think maybe a vague hundreds of thousands would work better, but I can go with hundreds instead if that doesn't work. I do have it in mind, however, that for planetary warfare a special class of autowar is used that's essentially a flying fortress which uses gravity manipulation technology to pull up resources, which it then uses to manufacture said ground and atmospheric based units. Kind of like a World Devastator from Star Wars, but less indestructible. And nowhere near as stupidly OP. So the numbers can easily fluctuate based on the narrative if need be with that idea, either because resources have run out, the gravitational tractor has been countered or disabled, etc.

For weaponry beyond that, I'm really just thinking these ground forces use standard lasers and kinetic/explosive weaponry, unless plague bombs or gray goo type weapons are allowed, but that might be a bit much. These wouldn't be like physically accurate lasers either, but Star Wars style ones, where it's akin to a slow moving (comparatively) bolt of superheated plasma that can be reflected or absorbed with the right materials. And obviously dodged.
