Editing Warhammer 40,000/7th Edition Tactics/Tau (section)

===Vehicle Battle Systems===
* '''Advanced Targeting System:''' It gives "To Hit" Rolls of 6 Precision shot. A trollworthy thing if your Rail Gun can insta-gib an enemy HQ hidden within meatshields (2+ LoS says "not likely", but hey, a chance is a chance), but there are plenty of snipers in the codex that are better suited for that role. Doesn't make it any less hilarious though. Still, because most of vehicular firepower comes as Blast weapons or from drones, it might not see much use.
* '''Automated Repair System:''' On a 6 it repairs a Weapon destroyed or Immobilized result. It's cheap and could give you back what you once thought lost. Use if you have points to spare.
* '''Blacksun Filter:''' While these come as standard on Battlesuits, they still have to be paid for by vehicles. It lets you ignore Night Fighting and Blind effects. As it's so cheap, it's hardly points wasted even if you don't ever get to use it. Remember vehicles are not affected by Blind anyway. 
* '''Decoy Launchers:''' 4+ invul to glancing or penetrating hits caused by the Interceptor rule. By far the best use of this is on the flyers. Makes those nasty quad guns seem like a bad dream. Sadly it has little other use.
* '''Disruption Pod:''' It gives a +1 to your cover save, so it effectively acts like Stealth while still being stackable with it. Not as brokenly powerful as before, but still pretty damn good. 3+ in 7th in the open is great. Detach your drones and put them between your tank and your enemy and then yeah, 4+ cover without the disadvantages of Jink. Always buy it for your tanks, never for aircraft, unless you expect jinking a lot (which you don't unless you brought buckets of markerlights).
* '''Flechette Discharger:''' Fires a number of S4 hits equal to the number of folk in contact with it. Scares lightly armoured grenadiers (meltabomb vets, wyches and swooping hawks comes in mind), but MEQs don't give a shit about it.
* '''Point Defense Targeting relay:''' The S5 and below weapons can overwatch. Gives the vehicle Supporting Fire as well. Autotake on Devilfish (only if you grab SMS), and reasonable on Tanks if your local meta uses assault units. Perfect for Tetras and Sky Rays, if close to your units.
* '''Sensor Spines:''' Gives Move through Cover. Another case by case one. Useful for hiding tanks in cover, especially with Disruption pods, but almost worthless on fast skimmers and definitely worthless on flyers. Since Skimmers ignore Vertical Move Distance, use them to go from ruin cover camping to ruin assault range kiting in 3". If it fits, it sits!
