Welcome to Gaia! ::

Let's talk stupid here,

I really think the Taurox would look better with wheels.

It's hilarious that GW thinks Guard needs to pay premium prices for their special close combat weapons, as if you want them to get stuck in melee with those stats! talk2hand

The Taurox is still ugly. emotion_donotwant

Directed Firestorm Sanctioned - Ordered unit must make a shooting attack. All weapons fired by models in the ordered unit are Twin-Linked.

Searchlight (Yeah, that thing most Imperial vehicles come with standard that people forget to use)
Relic Plating (Gives the vehicle the Adamantium Will special rule)
Doze blade (No, I'm not sure where it goes on the model either)
Storm bolter (I don't think this needs explaining. It's the same one every Imperial army has)
Recovery gear (Gives the vehicle the ability to become mobile again like a Rhino if it's immobilized. Does not give back Hull Points. (Costs the same as a Melta bomb)
Smoke launchers (Not standard here apparently)
Extra armour (Just in case you're worried about being Stunned)
Fire Barrels (First time an enemy unit attempts to charge a vehicle with these they suffer D6 S4, AP5 hits allocated randomly. For the cost of a meltagun, I would probably take this if I was worried about things punching my vehicles)
Hunter-killer missile (the same one that no one takes, you can even see the dust!)
Augur Array (New kit that works like a Teleport Homer)
Camo Netting (only helpful if you sit still)

Army List

Wouldn't be much of a codex if we didn't have an army list to build off of, now would it?
HQ

Commissar (may upgrade to Lord Commissar)
Militarum Tempestus Command Squad (the unit you'll probably see more often as it can give orders, plus Clarion Vox-Net, which allows all friendly units from Codex: Militarum Tempestus within 18" to use the Tempestor Prime's Leadership for Fear, Morale and Pinning tests)
Troops

Militarium Tempestus Scions (Starts at 5 models, can go to 10)
Fast Attack

Taurox Prime (also a dedicated transport for Militarum Tempestus Command Squads and Militarium Tempestus Scions)
Valkyrie Squadron (1-3 Valkyries, still carries 12 models despite rumors have claimed. Not a dedicated transport option)

I told you that we'd be covering these. There are two in total.
