Rescue! 

Space Marines vs. Eldar

Forward units of the Storm Lords arrive on scene - two tactical squads, and a scout squad crest the hill, and spy the small valley below them. Warnings go off on their tactical displays, as sensors pick up a large alien host across from them, headed towards the same valley.   As one the marine units crest the rise and only then separate, the only noise other than the engines of their rhinos the voice of veteran Sergeant Eban Allan on the comm link.

Turn 1:

Storm Lords

from the southern edge of the battle field, a storm lord rhino and scout squad advance, while to the west, above the ruined temple, another rhino moves towards the potential artifacts.

Beta Squad unloads to investigate what could be an artifact at their feet. Alas, they come up negative. Behind them, in the ruins, the scout squad secures another potential  piece, however their initial excitement is crushed by the reality that the piece the hold is just another piece of space junk.

Craftworld Orkan Baharr

The Eldar are quick to counter the monkeigh threat   - moving in mass against the humans, three deadly vypers crest a ridge, their intent obvious to the monkeigh transport and its contents.   The vypers fire, ripping the tread off of the human transport, immobilizing it.

A falcon grav tank and wave serpent quickly move across the battle field, followed closely by the main Eldar war host.  Fortunately for the Monkeigh, these units are denied a shot by the large hill in the center of the battlefield.
