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

====Battle Brothers====
Every army of the Imperium, which is as follows:

*Blood Angels - Nice because you can get death company to go rip people's head off while they're at it. Stick a Sanguinary Priest in there for FNP for your guardsmen.  Mephiston can do everything your army can't. Love it.
*Grey Knights: If all you want is tough marines, Deathwing Termies (from the Dark Angels) are probably better since they're more gun-tastic anyway, after CC has been nerfed so much over the past 2 editions. However, value is found with an excellent beat-stick to save your asses in case it comes to assault. Also, Hammerhand on a squad of Guardsmen from a Librarian, who should also be armed with a Nemesis Daemonhammer, coupled with Force. Any monster will think twice before charging your blob.
*Dark Angels - BS2 Overwatching, Stubborn, green SPEHS MUHREENS that can stand in front of your gunline and force the enemy to charge them first and get shot to shit by the Angelic Dakka. Their Terminators and Bikes are still the best in their categories ever.
**SWEET MERCIFUL EMPRAH, AZRAEL ''Ahem,'' if you're feeling particularly trolltastic, you can attach Azrael to a 50-man blob of guardsman for [[AWESOME|50 4++ invul saves]] fearless, and either Furious Charge or Feel No Pain within 3" of an Objective. Then just grab some deathwing termies (or ravenwing if you're kinky like that) and deepstrike them behind enemy lines, and watch the madness ensue. Throw in a psyker with prescience for rerolls to hit, or better yet a priest to reroll the 4++, giving you better saves than storm shields and making your opponent weep bitter tears. This cheese has officially upped Dark Angels to the number one allies for IG (in this writer's opinion at least).
**Throw in a priest with some Deathwing you don't plan to deepstrike (at least without a drop pod) for a cheap set of rerolls. A bit fragile, but they are much cheaper and provide better buffs than a chaplain.
**Can be done with any Marine list, but I'll put this here. With 7th edition, Battle Brothers can take allied transports. You can fit 5 Ogryns/Bullgryns and one priest in a land raider crusader--with all the fun that only an assault vehicle can offer. Inquisition get access to Land Raiders too, so if you want, do it with them as allies.
*Space Wolves - If you don't mind the yiffing, they've got some nice firepower to add in the form of Longfangs. Grey Hunters/Thunder Wolves are a nice option too with counter-attack to save your gunline's ass when it comes to close combat.
*Space Marines - The new book gives you loads of new options. Librarians now have Divination, and the new Gladius Strike Force looks insane.
**The Skyhammer Formation absolutely drips with cheese. Combine with Elysian Allies for Deepstrike upon Deepstrike insanity.
**Fun thing to try with non-Imperial Fist Devastators: pop a Primaris Psyker with them. Have him cast Divination, and then order "Bring it Down!", since Monster/Tank Hunter applies to everyone in the unit if a single model has it. Watch as light-medium Tanks and Monstrous Creatures go pop, and if you have Lascannons, even Land Raiders melt (explosively) like butter in a furnace.
** Bring the Libraius Conclave formation for some utter, utter cheese. Casting loads of powers on a 2+? Yes please. Have some 4++, rerolling, full BS Overwatch, Invisible 50 man guard blob.
** Techmarines can be better than Guard Techpriests, especially if they're Iron Hands and tooled up with a Servo-Harness. Put one on a bike and he can keep up with tanks, and the combination of T5, W2, 2+, 6+ FNP and Jink should keep him alive to keep your tanks alive.
*Skitarii - Brand new Adeptus Mechanicus robot soldiers. You bring armored support, they bring the 4+ save infantry with excellent weapons, for cheap too. These guys can also make great use of your Chimeras and other armored transports, something that the Skitarii codex has none of. Also the Skitarii can be very effective in melee, where the Guard usually aren't.
*Cult Mechanicus - Like the Skitarii, the Martian death robot army lacks transports which you can provide. Also artillery, large blast templates and air cover. So what do they bring then? The HQ Techpriest Dominus is essentially one of your 0-3 enginseers on steroids. Taking a mechanized army? A tank army? Bring him. He will please you with his repair on 2+ ability and his ability to fire two weapons. The real cheese comes with the formations. Many of them are excellent and have something to offer the Guard. The Cohort Cybernetica can pack so many heavy phosphor blasters that those cover camping jinking space elves look like disco balls. The Tau turn blue(r) with envy as you steal their markerlight shenanigans. MEQ barbecue is also on the cards as each Kastelan fires 6 S6AP3 shots, half of which are twin-linked. Bring an Elimination Maniple, add some Divination and drink the tears of your opponents as you fry their TEQs with cover ignoring plasma or crunch their vehicles with heavy grav cannons.

However, the best source now has to be new Inquisition. Why?
*You only need to take an Inquisitor minimum in the detachment, it may as well be like selecting special and generic characters from this Codex.
*Have a ton of absurdly useful goodies, including:
**Servo Skulls that prevent the enemy from scouting or infiltrating within 12 inches, as well as reducing scatter on your pie plates by D6 when shooting at units within 12" of them. Only 3 points each.
**The Liber Heresius, which can give your blob hilarious shit like splitfire, counterattack, hatred, fear, or scout, though only once per USR.
**The Psyoccolum for giving an ENTIRE UNIT OF 50 GUARDSMEN/CONSCRIPTS BS10 when shooting at units with Psykers inside, so say fuck you to Joe Schmoe with the Daemon Prince or the faggot with Spiritseers.
**Ordo Xenos Inquisitor, equipped with a conversion beamer. He can benefit from the split fire orders when attached to a guardsmen squad, meaning that you are free to make full use of the S10 AP1 blast. He gives them stubborn and they can use his Ld 10 for orders, so he basically acts as a commissar as well. Spend another 30 points, and he is a primaris psyker with +1 ld, too. Overall, he can kick some serious ass.
**In fact, all the Ordo Inquisitors are Commissar-primaris psyker combos, but better, more customizable, and cheap.
*The henchmen selection is mental and incredibly varied, allowing for a warband that pumps out enough firepower to drop jaws. Up to 3 Servitors with Multi Meltas, a Jokaero Weaponsmith, 3 SW Acolytes, and priests that can also take various shit like combi-weapons, meltabombs and Eviscerators!
*Spam divination inquisitors, with a full allotment of primaris psykers, and say fuck my shitty BS. Followup with 2-3 Land Raiders filled to the brim with crusaders and/or (definitely and) death cult assassins, with a priest or 2 for shits and giggles (and eviscerators) and rush them forward. Suddenly the other player has stopped focusing on that rerolling gunline full of inquisitors and psykers and is worried about getting hatefucked by a bunch of death-cultists.

People who can't give you divination but might be worth a look:
*Sisters of Battle: Cool, but tricky. Acts of faith are always fun. Their priests are better than yours (well, can get more shinies, anyway), and Dominions make tanks cry. You can give their Exorcists Divination buffs, or attach a Primaris Psyker and use some orders to make their basic infantry hit hard. (Ignore Cover or Pinning, re-roll to hit from Divination, re-roll 1s to wound from Faith - infantry rapetrain with no brakes.)
*Knights: Nothing much to say except yes.  You've already got the firepower to back it up, meaning you can send your knight into the center of your enemy's formation to crush things in CC.
** Alternatively run an oathsworn detachment of Knight Crusaders and surround them with meatshields. For the cost of a stock Land Raider, you can field 50 guardsmen. For the cost of a Leman Russ you can field 50 conscripts. For a minimium-sized terminator squad in a tin can, you can have a screen of 100 bodies plus their overworked platoon commander. Bring blobs supported by shooty knights and watch your opponent's eyes go very, very wide.  
*Officio Assassinorum: While not an official army, this dataslate gives the guard some specialized killers. Vindicares have the range and firepower to pick off specific threats (Hidden Powerfists, Nobs, Priests), Callidus to pop out, Culexus for anti psyker killing, and Eversor for just plain killing.

There is a very, very unfriendly way to do allies: from the FAQ on Forgeworld, any type of Guard can ally with each others with Battle Brother level, which means Codex Guard can now allies with Death Korps of Krieg: Siege Regiments, Death Korps of Krieg: Assault Brigade or Elysian Drop Troops and as well as... Death Korps of Krieg: Armoured Battle Group and Armoured Battle Group to get a maximum of 8 more tanks! Use this as your advantage so you can field bunch of artilleries in your Codex IG FOC while another bunch of tank in your ally ABG FOC in high point battles. Beware this may result in a loss of friends in your local community.
