Actually, this isn't the case. Put the missile in a highly elliptical orbit
and you can arrange for it to approach L2 from any direction desired. Of
course, this would take more fuel and considerably more time, but it would
get the job done.

Either nukes or chem/bio warheads. Bomb pumped X-Ray lasers would probably
be a good choice as well, but we've never seen that tech in Gundam so it can
probably be discounted.

Well, it depends how big and heavily protected the missile is. The Feds
could just slap a big hunk of DU on the front end and let the sand ablate it

As I pointed out, missiles can be fired from any direction, so you'd need a
full sphere.

Also, how do you propose to keep the sea of sand in one place? There are
basically three choices for any object in the vicinity of L2. Either put it
in the Lagrange point proper, which wouldn't be much use in this case. Put
it in some sort of lunar orbit, which would mean the cloud would orbit the
moon, rather than staying by L2. Or put it in a halo orbit about L2. If I
recall correctly (and Z can probbly correct me if I'm wrong) a halo orbit
about the first three Lagrange points must be in a plane perpindicular to
the Earth-Moon axis. Thus it would be impossible to even put a cloud
directly between Side 3 and the rest of the Earth sphere.

The Federation counter to a defensive system like this would probably be to
launch a lot of missiles on different vectors, timed to arrive from all
directions at the same time. No matter how good a defense is, there is a
point at which it will become saturated and any further missiles will get
