Orbital bombardment! If there was anything that brought landbound mechs despair, then having giant objects thrown at you from the sky topped the list.
No one on the surface possessed the power to withstand bombardment from orbit!
While plenty of advanced ground weapons existed that could give ships orbiting leisurely above a planet's atmosphere a nasty surprise, none of the forces and outfits in the Aeon Corona System could afford such extravagant toys.
Neither the Vandals nor the Swordmaidens possessed any means to withstand hundreds of tons of metals and minerals fused together into a single, resilient package.
Perhaps if they threw everything at a single artificial meteorite, they might be able to fracture it and cause it to crumble into smaller pieces.
Yet those pieces would still descend along the same course!
