Mortarion + Destroyer Squad

[Hesh Kadesh]

Expensive as hell, but;

 

Destroyer Squad, +5 additional Destroyer Space Marines, Meltabombs, two Missile Launchers equipped with a Suspensor Web and Rad Missiles, Destroyer Sergeant with Power Axe, Artificer Armour, Phosphex Bomb = 345

Mortarion = 425

Spartan Assault Tank, Flare Shield, Armoured Ceramite, Auxiliary Drive, Havoc Launcher = 360pts

 

= 1120

 

The potential of getting into combat second turn with the meatiest of opponents, and just launching 2 Phosphex Bombs, 2 Rad Missiles, a Havoc Missiles with poison 4+ (just a thought, does the poison allow the rerolls when shooting? Going by RAW is obviously "nah", but is this oversight and should be "yah"?) and a Poisoned 4+ Frag Grenade, and the pistols; which is then followed up by charging into an assault against T3 opponents.

 

Of course, it's not exactly at the standards of a similar number of Firedrakes plus Vulkan in a tricked out Covenant of Fire Spartan, but still.

If you can toss a Primus medicae in there with a Barbaran Thuribule then yeah, GG.

I keep forgetting about the relics. Even better, especially if you nix their Vexilla and Ld9.

Woe be to thee who fields Monstrous Creatures against such a unit!

 

Edit: Bonus points if you add in the Antomantic Pavise Deredeo for +1 Invulnerables
