How Tau interact with Overwatch and Interceptor

Please note:  The following text is based upon my opinion and interpretation of the rules in Warhammer 40k 6th Edition.  I've tried to back up everything I've mentioned with facts and definitions from the Basic Rule Books and Codexes to try and make my conclusions seem logical.  Your own mileage with this may vary.

INTRODUCTION


As a Tau commander my primary goal is to drink the tears of my enemy...  Usually these are collected in receptacles knows as "Tear Cups".  Tau have got some of the most over-powered and competitive units currently available in the game, and some of their wargear seems positively broken.  These facts alone are enough to make your opponents cry.

For some people, the Multi-Tracker is probably the most broken item of equipment in the whole Codex.  This item is automatically included with every Suit the Tau can field (so Stealth, Crisis, Broadside and Riptide) and what it does is pretty amazing.  This is the official definition from p69 of Codex Tau Empire:

Multi-Tracker
A model with a multi-tracker can fire an additional weapon in each Shooting phase.

To me, this seems straight forward enough.  In each Shooting phase I can fire an additional weapon!  Now we have to make a basic assumption here... By Shooting phase, I would have to presume it means my own Shooting phase and does not include my enemies Shooting phase.  This is because I don't normally shoot in my enemies Shooting phase and the word "additional" would infer that at least one weapon has been fired.

Worth noting at this stage that the Multi-Tracker does not confer any rights per se to fire weapons in my Enemies turn, or to fire any weapons in any other phase other than the Shooting phase.

What is the Shooting phase?   Let's define that for a moment... In fact, it might also be worth while reminding people of the entire Player Turn (with the Game Turn consisting of one Player Turn for each Player), just so we are clear on the separation (see Basic Rule Book p9):

Movement phase 
Here, you move any of your units that are capable of doing so.

Shooting phase 
You now shoot with any of your units that are capable of doing so.

Assault phase 
During the Assault phase, units declare charges in the Charge sub-phase and trade blows with their enemies in the Fight sub-phase.  All units in close combat fight, this is an exception to the normal turn sequence in that both sides fight, not just the side whose turn it is.

Hopefully this is simple enough.  When it is your turn, you may move in the Movement phase, shoot in the Shooting phase (and this is where the Multi-Tracker allows you to fire an additional weapon) and you may declare a charge and resolve melee attacks in the Assault phase.

Interestingly, it's the Assault phase where things start to unravel... In the Assault phase, once you have declared a charge against an enemy unit, this unit gets to declare an Overwatch attack against the charging unit.  This is defined quite clearly in the Basic Rule Book on p21:

An Overwatch attack is resolved like a normal shooting attack (albeit one resolved in the enemy's Assault phase) and uses all the normal rules for range, line of sight, cover saves and so on. Unlike a normal shooting attack, Overwatch cannot cause Morale checks or Pinning tests. Any shots fired
as Overwatch can only be fired as Snap Shots (see page 13 for more on Snap Shots). Therefore, weapons and models that cannot fire Snap Shots cannot fire Overwatch.


So the big question a Tau Commander is going to ask:  Will the Multi-Tracker allow me to fire an additional weapon during an Overwatch attack?

In order to answer this we will require a definition for a "normal shooting attack" which is directly referenced within the Overwatch rule.  Luckily such a definition exists in the Basic Rule Book on p12, but you have to look really hard to find it:

During the Shooting phase, a unit containing models armed with ranged weapons can be nominated to make shooting attacks.

And how many shooting attacks can a model or unit make per Shooting phase?   Check out p51 of the Basic Rule Book:

Unless otherwise stated, if a model has more than one Shooting weapon, he must choose which one to shoot - he cannot fire both in the same Shooting phase.

As it seems to be that a shooting attack is made by a shooting weapon, I think it's finally pretty safe to make the following definitive statement:

A Multi-Tracker does not affect the number of shooting attacks that you are able to make during an Overwatch attack, as this occurs during the enemy Assault phase.  You are therefore limited to a single Overwatch attack consisting of a single shooting attack.


WHAT ABOUT INTERCEPTOR? 


For those of you that are unfamiliar with the Interceptor rule the relevant bit is on p38 of the Basic Rule Book:

At the end of the enemy Movement phase, a weapon with the Interceptor special rule can be fired at any one unit that has arrived from reserve within its range and line of sight.

Although you could say that Interceptor is a shooting attack made in the enemies Movement phase, there is no definition of Interceptor except as a characteristic of a weapon.  For the Tau, this is particularly fun for a unit with the following bits of kit:

Early Warning Override
All weapons on a model with an early warning override have the Interceptor special rule. 

What this means is (unlike Overwatch) a Tau unit with Early Warning Override could fire ALL it's weapons at the end of the enemies Movement phase.  Of course, there is a downside to doing that, but you'll have to read the rule entry in the Basic Rule Book to find out more.


TARGET LOCKS


If you want your mind completely blown, check the following piece of Tau wargear from p69 of the Codex Tau Empire:

Target Lock
A model with a target lock can shoot at a different target to the rest of his unit.

Read that again, then tell me if a model with a Target Lock and an Early Warning Override can fire at some other random target that hasn't arrived from Reserves or Deep Strike that turn, so long as the rest of it's unit fires at the one that has?  Tell me if this means a model with a Target Lock can fire at a non-charging unit during Overwatch while the rest of the unit fires at the charging unit?

Now THAT is completely broken if you ask me.

OTHER TAU STUFF... DOES IT WORK WITH OVERWATCH AND/OR INTERCEPTOR?


Advanced Targeting System - Doesn't work (Shooting phase only)
Blacksun Filter - Works
Counterfire Defense System - Works (of course!)
Drone Controller - Works
(Networked) Markerlight - Hell yeah!
Pulse Accelerator - Works
Velocity Tracker - Works (any shooting attack) 
Command and Control Node - Doesn't work (specifically stated)
Multi-Spectrum Sensor Suite - Doesn't work either!
Neuroweb System Jammer - Only works in the enemy Shooting phase, so no Gets Hot when they shoot Overwatch or Inteceptor :(
"Through Unity, Devestation" - Doesn't work (Shooting phase only)
"Predator of the Skies" - Doesn't work (Shooting phase only)
 Invocation of the Elements (Storm of Fire) - This is AWESOME in Overwatch!  Could work with Interceptor if you had a Pulse weapon with Interceptor.
Nova Reactor (Ripple Fire) -  Doesn't work.  It's defined as allowing the secondary weapons to "fire twice this turn" and count as having fired once, but because there is a rule about Turns on page 9 of the BRB states that "a turn" refers to a "player turn" unless it specifically states "game turn", and because Ripple Fire is activated at the start of the Tau players Movement Phase, it will only be active until the end of the Tau players turn.
Volley Fire - Doesn't work (Shooting phase only)
Structural Analyser - Doesn't work because Overwatch attacks are Snap Shots.  Would work with Interceptor Darkstrider somehow got hold of a weapon with that Special Rule.... Like a gun emplacement.
Command Link - Doesn't work (Shooting phase only)

RUNNING


Running is defined on p14 of the Basic Rule Book.  The pertinent point is "In their Shooting phase, units may choose to Run instead of firing".  Of course, if you think Multi-Trackers will work in Overwatch, you must also (by virtue of the "Shooting phase" wording on both rules) allow running instead of shooting during Overwatch.  Good luck trying to get your assault units into combat!


MONSTROUS CREATURES


It's worth noting that there is a rule regarding Monstrous Creatures defined as follows:

Monstrous Creatures can fire up to two of their weapons each Shooting phase - they must, of course, fire both of then at the same target.

Because of the Shooting phase definition within this rule, the argument above applies to Monstrous Creatures, in exactly the same way as they do for Multi-Trackers.  Bear in mind that if you happen to have a Monstrous Creature with a Multi-Tracker, they would be able to fire 3 weapons in the Shooting phase, if of course they had 3 different weapons to fire.  They still wouldn't be able to fire all 3 in Overwatch.


GUNSLINGER


A carefully hidden rule in the Basic Rule Book... Defined as follows on p52:

All models with two pistols can fire both in the Shooting phase.  This follows the normal rules for shooting.

Needless to say, the same thing applies to Gunslinger as to Multi-Trackers and Monstrous Creatures!

  1. Nova Reactor (Ripple Fire) does NOT work for overwatch and interceptor. Pg. 9 BRB, "Whenever a rule refers to 'a turn' it always means 'player turn' unless it specifically refers to a 'game turn'." It's in bold if that makes it any easier to find when you verify my claim.

  2. Question for you. Do you have any good ideas on how to utilize breacher teams on the defensive? Its seems that we are going to be forced fire at the enemy while he is farthest away or not fire altogether, rather than wait until the enemy is right on us for maximum effect. Thoughts on ways to get around this?

  4. "In their Shooting phase, units may choose to Run instead of firing". Here it clearly states that you can run when in the shooting phase. But the rules for overwatch specifically state that you may make a shooting attack that follow the same rules as the shooting phase. Notice that you must make a shooting attack. That's why you can't run in overwatch. And if you follow the same rules as if in the shooting phase, then you must adhere to the rule that states models "cannot fire both in the same Shooting phase". Well, if it isn't a shooting phase then doesn't that mean the overwatching unit can fire all its weapons? Furthermore, how can you claim a unit is restricted by that rule, yet the rule for Multitrackers doesn't apply?
