Seeing as KMB is obsessed by my obsession with tanks:
Here's a mech list:
IG with
BA allies:
HQ: CCS - 180
3 x plasma gun, astropath (gets my reserves on faster), chimera
Troop - platoon 490
PCS - 3 x grenade launcher, chimera
Infantry squad - krak grenades, plasma gun, chimera
Infantry squad - krak grenades, plasma gun, chimera
Infantry squad - krak grenades, plasma gun, chimera

PCS - 2 x grenade launcher, chimera
Infantry squad - krak grenades, plasma gun, chimera
Infantry squad - krak grenades, plasma gun, chimera

Fast - Vendetta - 130
Fast - Vendetta - 130
HQ - Librarian - 145
Terminator armour, storm shield, shield of sanguinius, wings of sanguinius
Troop - Assault squad - 110
Melta gun (into stormraven)
Heavy - Stormraven - 200
Bloodstrikes, assault cannons, multi meltas
Total - 1850
Vehicles - 11 (of which 3 are flyers)
Troops - 92
Scoring units - 10
Fairly simple again. Weather the storm of long range shooting on turn 1. The librarian joins the CCS (if he can in a vehicle - otherwise he stands behind the tank wall) and casts shield. Small squads that get close are enganged using wings.
Flyers arrive & kill everything.
End.
