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

====The Forces of the Imperium:====
*'''Space Marines:''' With the loss of Battle Brothers, you need to be creative in using Marines. Thankfully all-bikers from both Scars and Ravenwing can still work as they have great mobility and can be left alone for the most part. Assaulty armies like Templars and Sharkies are better as distraction, but don't bring too much as your primary advantage is still shooting. Landspeeders works like a better Piranha, pretty good for dealing with covered blobs if you don't want to commit your suits.
*'''Imperial Guard:''' If you want to bring all-suit army, IG's artilleries can be a great boon in dealing with things you'll have difficulty, like MSUs. IG blobs can also screen your gunline, but let them die first or stay away from assaults as you still need to shoot them. IG tanks are best used as distraction that's capable of wreaking havoc if left unchecked.
*'''Dark Angels:''' As stated above, go with Ravenwing. Deathwing Knights are also excellent anti-everything deathstar though needs careful deployment and lucky deepstrike. (you'll at best only bring one biker squad to help them, so it will be expensive tax but worth it if you know how to use)
*'''Space Wolves:''' Mostly the same uses as the vanilla above, save for a better flyer and are far better in assault.
*'''Blood Angels:''' Death Company with jump packs/Sanguinary Guard supporting your deep striking Crisis Suits for a deadly one-two punch down the board.. Plus Assault Squads on foot in front of your firing line to help hold the line when they do reach you, better than Kroot in every category but points cost. Want to bring a Dreadnought and an elite jump squad? Grab a Furioso Librarian Dreadnought and get a built in psyker and dreadnought and your elite jump squad while still maintaining a bound allied force. All with built in furious charge for extra punch. What's not to like about this combo except for having to remain six inches apart.
*'''Grey Knights:''' Primary use is psyker defenses and Purifiers, though Eldar are better by virtue of being Convenience. Paladins may work if you need tough units.
*'''Inquisition:''' Think of Inquisition as a toolbox that capable of filling any holes you need, packed in mobile Chimera or Valks. Though with downgrade to Desperate Allies, pay attention to movement phases.
*'''Sisters of Battle:''' Sisters excel at annihilating vehicles with Melta (Dominions) or rooting hordes out of cover (basic Sisters, Heavy Flamer Retributors). Tau are good at this too, but Crisis Suits are the unit of choice for both. Taking Sisters could let you free up some XV8s for other purposes, like hunting transports (missiles) or TEQs (plasma/fusion). Saint Celestine and Seraphim or Battle Conclaves could provide a reasonably good assault interceptor, too. Skip the Repentia, though - you need a Stormraven or a Land Raider to use them effectively.
