Corridan IV is a planet being invaded by Clan Ghost Bear.  The local
government forces, supported by two mercenary companies, are trying to
resist the invasion.  During a recon mission, the planetary defenders run into a
Clan star supported by several points of elementals.  A small town in a remote
canyon becomes a battlefield.
This is the terrain.  There is a wooded ridge to the
East and a barren ridge to the West.  The bottom
of the photo is North.
The defenders enter the canyon
from the South.
A star and some elementals
from Clan Ghost Bear enter the
same canyon from the
Northwest.
The Clan forces move onto the West ridge.  
The Lyran ("blue") forces also move onto the
West ridge while the mercenaries ("green") try
to stay out of sight and make a flanking move
along the wooded East ridge.  Tanks and
hovertanks form a screen along the canyon road.
The battle is joined on the West ridge while
Clan elementals try to delay the flanking
movement to the East.  The Clan mechs easily
overpower the Inner Sphere forces, but take
damage in the process.
The mercenaries and the Clan mechs exchange
fire from opposite ridges.  The Clan
elementals fearlessly move in for a kill.
But, some mercenary reinforcements from a
nearby patrol come in from the South and shift
the balance.
The Clan forces are defeated in what can only
be describes as a pyrrhic victory for the
defenders.  Without outside help the planet
will ultimately fall to the clans.
