Editing Warhammer 40,000/Tactics/Militarum Tempestus(7E) (section)

===Orders===
Unlike the ordinary Astra Militarum, the Tempestus forces have their own unique orders.
*'''Directed Firestorm Sanctioned!''' - When shooting, the ordered unit gets twin-linked.
*'''Autonomous Fire Sanctioned!''' - Ordered unit gets Preferred Enemy when shooting a target.
*'''Close Assault Doctrine Sanctioned!''' - Ordered unit gets Crusader for the rest of the turn.
*'''Advance on Target!''' - Ordered unit gets Fleet for the rest of the turn.
*'''Suppression Doctrine Sanctioned!''' - Ordered units firing Hot-Shot Laspistols/Lasguns can only fire one shot, but that shot gets Sniper and Pinning.  Also, the scions cannot charge in the assault phase.
*'''Elimination Protocol Sanctioned!''' - Ordered unit gets Rending against an enemy MC/Vehicle.
You may have noticed these orders are not as clear-cut as standard Guard orders; a lot of them seem like they're trying to do the same thing. But generally you can split them into two categories: 'Move' orders and 'Shoot' orders (unlike Guard, there is no 'Forwards, For the Emperor!' equivalent so you can't run and shoot at the same time). Let's talk about each in turn:
====Move Orders====
*'''Close Assault Doctrine Sanctioned!''' - Ordered unit gets Crusader for the rest of the turn.
**Much better when trying to move across the battlefield, since it gets you 2D6-take-the-highest instead of a simple reroll.
*'''Advance on Target!''' - Ordered unit gets Fleet for the rest of the turn.
**Better when trying to get into an assault, since it affects charge distances, while CAD does not.

However, if you're about to charge some Tau, or similarly weaker-than-Guard troops, and you're ''certain'' you can make the charge, CAD can help you sweep a big blob.
====Shoot Orders====
These are more complicated. The desirable order depends on what you're shooting (obviously), with the big differences being between shooting at Infantry, Vehicles, and MCs:
=====Shooting at Infantry=====
*'''Autonomous Fire Sanctioned!''' - Ordered unit gets Preferred Enemy when shooting a target.
**The best in general, as Preferred Enemy is ''slightly'' better than Twin-Linking (about 0.5% better, if you run the math).
*'''Suppression Doctrine Sanctioned!''' - Ordered units firing Hot-Shot Laspistols/Lasguns can only fire one shot, but that shot gets Sniper and Pinning.  Also, the scions cannot charge in the assault phase.
**Best if you have lots of '''HSLs''' and you're outside 12"; ''also'' the best order ''within'' 12" if you have lots of '''HSLs''' and your target is toughness 5 and above, or if your target has a 2+ save, because Sniper shots get Rending on a to-wound roll of 6.
**''Special Note:'' This is by far the best order against most, if not all, types of '''Monstrous Creatures.''' If Magnus the Red is on the board, you know what to do.
*'''Directed Firestorm Sanctioned!''' - When shooting, the ordered unit gets twin-linked.
**Blast weapons are not affected by Preferred Enemy, so use if you have lots of '''Grenade Launchers''' or are manning a Macro-Cannon emplacement.  Similarly, use if for some reason you have lots of '''Flamers'''.

=====Shooting at Monstrous Creatures=====
This one's a bit all over the place.  If you're using ''melta'' or ''plasma'', consult the above advice (treating your target as high-toughness infantry); the same typically applies to ''HSLs''.
*'''Elimination Protocol Sanctioned!''' - Ordered unit gets Rending against an enemy MC/Vehicle.
**Use this with anything that '''''isn't'' melta, plasma, or HSLs'''.
***Exception: if your target is '''Gargantuan''', your target is '''within Rapid Fire range''', and you are firing '''HSLs''', use this, as GMCs downgrade Sniper to Rending and, in practice, can't be pinned.
=====Shooting at Vehicles=====
*'''Elimination Protocol Sanctioned!''' - Ordered unit gets Rending against an enemy MC/Vehicle.
**Use this in general, as it can get you a lucky pen (in the case of Plasma you can pen Land Raiders).
*'''Directed Firestorm Sanctioned!''' - When shooting, the ordered unit gets twin-linked.
**Finally gets some use with '''meltas''', since you don't need Rending and Preferred Enemy doesn't work on penetration rolls.
