- I'm sure the Moon colony would be the main supplier of armor for armored
- military satellites. That doesn't mean they'd own them, or that they
- would have a monopoly on them. Sure, it's more expensive to launch the
- mass needed for armor from Earth, but it *can be done* -- the cost is
- not prohibitive under the assumptions necessary for a lunar colony to
- exist at all. And the lunar colony is not going to be able to afford
- Earth-sized military budgets for a very long time. Their advantage,
- while noticeable, is nowhere near enough to put them in a commanding
- position over a much bigger and richer neighbor.

- Direct hits are already-demonstrated technology. You don't really need
- nuclear weapons for this kind of thing; a direct hit from a ton of sand
- will punch through that regolith layer pretty easily. Knocking out
- satellites is *easy* -- they can't maneuver very much (especially if
- they're hauling many tons of armor around), reaching orbital altitude
- is much easier than reaching orbital velocity (a Scud with suitable
- guidance and course-correction systems would be a workable antisatellite
- weapon), and their own orbital velocity makes warheads almost superfluous.
