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

===Battle Brothers===

*'''Adepta Sororitas:''' Why? All the good units they have to offer are the Priests and Jacobus (Much cheaper and better than chaplains for War Hymns to potentially give your Death Company rerolls on wounds and any saves), you already have fucktons of flamers and meltas while your tac marines can do the same as normal bolter babes with +1 S/T. However, putting 4 Dominions with meltas in 3 drop pods can be great, especially considering the Dominion act of faith ignores cover. 4 meltagun shots that ignores cover? Great for tank hunting.
*'''Adeptus Mechanicus/Skitarii:''' Skitarii bring numerous, cheap and flexible troops that can provide a variety of roles that compliment a BA force. Ruststalkers/ Infiltators add specific melee counters and will do will charging something that the Death Company do too. The Army is Fast enough to keep up and for real lulz you can put them in pods for some super strong alphastrike. Plus Array Onagers are the death of flyers. Period. Mechanicus on the other hand bring spades of Grav and or MC, something the BA also lack.
*'''Dark Angels:''' - A very good combo with Blood Angels, as they are the more shooty and resolute marines compared to your own quick moving, melee marines. You can also perform really good alpha-strikes with lots of <s>turn 1</s> TURN 2 with the new and improved Deathwing Assault special rule *cough sarcasm *cough Deathwing deep strike (particularly with [[Belial]]) and are one of the few other Space Marine chapters with access to divination, while this is no longer the go-to discipline as it was in 6th edition it combos especially well with Mephiston if he's already on biomancy steroids and will force your opponent to make panic induced mistakes.
*'''Grey Knights:''' It's just repeated deep-striking and a massive points sink. It's purely redundant like the Black Templars from Codex Space Marines.
*'''Imperial Guard:''' Excellent fire support for a up-in-your face army. A neat little army list is a CCS in a chimera (so he doesn't die if the enemy sniffs at him), a veteran squad with camo behind an ADL w/quad gun (or an infantry platoon if you have the points), and a few leman russes. All the fire support you'll ever need.  So for a CCS in a chimera, Camo veterans, and ADL w/quad gun and a Leman Russ, this all costs only 445 points (a little more or less depending on the Leman Russ variant and if you take upgrades for your Veterans or if you take an infantry platoon. With an ADL, the chimera isn't a necessity anyway). Alternatively, you could take them as meat shield distractions. But it's mainly recommended that you use them as long range fire support/ objective campers. Priests are highly welcome here to make sure that blob of Guardsmen can never die.
*'''Inquisition:''' Servo-Skulls and Mystics work really nice with your deep-striking units. Inquisitors also have hilarious shit like the Conversion Beamer (small blast that gets stronger the farther the target is from the Inquisitor holding it) and the Psyocculum which gives your units BS10 when shooting at units containing Psykers and Brotherhood of Psykers/Sorcerers. Death Company got the assault gear, Inquisition lays down a shooty advance. You can take Crusaders to suck up heavy weaponry and Power Weapons with their storm shields, so they are awesome meatshields too. Always a good choice. 
*'''Space Marines:''' Pretty nice alpha strike potential here if you throw in Vulkan He'Stan. You can also combine with White Scars or Raven Guard to come from nowhere to hit your foes everywhere, or bring Iron Hands for slightly more durable Predators, Devs and other support. Iron Hands benefit from your Pirest's FNP Aura. Yes, you can now give basic marines a 3+FNP with a Priest, IH IC from the Gorgon's Fist Strike Force + the native bonuses. Oh and Smashfucker has easy 2+ FNP with the Gorgon's chain. There is a reason the 9th Legion are so close to the 10th in number.
*'''Space Wolves:''' Long Fangs for epic long range shooting prowess, and Rune Priests. But Mephiston can do it better. Space Wolves with Counter-Attack make fantastic defensive allies to hold the line while Blood Angels go out and [[rip and tear]].
*'''Imperial Knights:'''' Nothing much to say but yes! Big scary, fast Super-heavies to give your target too many things to shoot at in too little time.
