Here's a first shot at a Tyrant's Legion list:
Huron
Centurion Ricimer, combat shield, power weapon, meltabombs
(5) Corpse Taker, power weapon, hellfire rounds, 4 Servitors in Razorback
(40) Legion Auxilia, 2 flamers, 2 grenade launchers, Prefect with power weapon, bolt pistol
(11) Legion Auxilia Armsmen, meltagun, heavy flamer, carapace, Master with power weapon in Chimera
(14) Legion SM Cohort, meltagun, 2 power weapons, Sarge with power fist, storm bolter
Medusa
Land Raider Crusader, multi-melta, extra armor
1500 pts
Termie Huron goes in the LRC with his 14 Cohorts and the Centurion can go with the Corpse Taker or the Armsmen in the Chimera. I'll probably swap out some weapons on the Chimera for flamers, to better fit the fluff (Huron liked flamers).
