Effects of single-ship orbital bombardment

This may have been covered on the TML before; if so, could someone
please point me towards the correct issue(s)?  If there is an
obtainable supplement/adventure to use as a reference, I'd like to
know that too.  Also useful would be real-world references with a clue
as to how to relate to MT numbers (preferably not too expensive a book).

What are the effects of orbital bombardment on un-hardened ground
targets?  What are the range of effects of a single-ship nuclear or
conventional missile attack on a target such as a troop encampment, a
starport, or a government building?  Obviously, point-defense and
area-defense will alter the situation, but if the effects on
defenseless targets are known then it should be relatively simple to
take into account other factors.
    I would basically like to know the capabilities of a battery-round
from a single missile turret (standard 3-missile rack), and from a
100t missile bay, using conventional and nuclear anti-ship munitions
as might be found on an average merchant ship. :-)
    Exact numbers are not too important as such, but I do want a feel
for the general capabilities of this sort of weapon.  If my players
want to take out a large downtown building, say, or wipe out a
guerilla camp, what are their options, assuming local air-space
superiority and an insufficient ground troop capability?  I imagine a
lot depends on how much collateral damage they are prepared to
inflict...?  (At least they have no anti-matter tennis balls.)
    How would the capabilities vary with TL?  I imagine precision
would improve greatly at higher TL's, but what about yield?
