Editing Warhammer 40,000/9th Edition Tactics/Imperial Knights (section)

===Adeptus Mechanicus===
The synergy with AdMech is strong, and with four of the nine Knight houses swearing fealty to Forge Worlds, this is also a pretty fluffy choice. Machine Spirit Resurgent is arguably the best stratagem in the codex, allowing you to use the top row of the damage table (which cancels out the Weary Machine Spirit burden). Benevolence of the Machine Spirit lets you ignore mortal wounds on 5+, essentially turning your knight's ion shield into a [[awesome|void shield]]. Knight of the Cog can give your Knights Canticles for the turn, which means cover in the open (for 2+ saves) or +1 strength (insane with Stomps and Death Grip). Note also that with the Imperial knight codex, the benevolence of the machine god stratagem is included, allowing you to use both it and the mechanicus stratagem on the same turn, which is a nice bit of flexibility.

Enginseers come at the low price of 35 points each including gear (and he can heal your Knights!) and both Rangers and Vanguard are 9 points per man, so a minimal battalion runs for as little as 205 points. While we're at it, consider the ''Necromechanic'' warlord trait to double up healing from your Enginseers--more with the Tech Adept stratagem. Monitor Malevolus also lets you recycle your CP and the opponent's CP on rolls or 6. There are also some really efficient units to fill out the Battalion with. Dunecrawlers and Mars Kastelan Robots offer great anti-tank or air and anti-horde or character, respectively. Stygies VIII Dragoons and Fulgurite Electro-Priests are great alpha strike melee options that can infiltrate at the start of round 1 for 1 CP each (Post BIG FAQ 2 that stratagem changed to a 9" scout move rather than a full infiltrate). The former gets a disgusting -2 to hit and has high volume, high strength attacks, which is great for vehicles and characters. The latter is riskier, especially if you aren't going first, but they vomit mortal wounds and can fight twice for 3 CP.
* An Onager Dunecrawler with Neutron Laser and 2x Cognis Heavy Stubber costs 125pts. The Neutron Laser is better than the Thermal Spear in every aspect. (48" vs 30", S12 vs S9, same AP, and more or less equal damage). Toughness-wise, due to the Armiger gaining a 5++ (Though unlike the Crab it only works against shooting), with the zoom bot still having 1 more wound, the onager has become more and more of a backline support tank. Due to the fact that Canticles are only availabe to the onager if you go Mars, that the Armiger has gotten tougher, and that with the more movement orientated 9th edition it is quickly becoming more optimal to just pick the Armored Psycopath. Just remember that that leaves a larger hole in your backline (some rangers will fill that up) and that as long as these medieval missiles are able to make it to the front lines you'll be glad to have some Feudalistic Fuckery within your ranks. Especially considering the overall lack of durable melee monsters the Admech are suffering from. You also benefit from having distraction carnifexs on the board. As even though they do cost 150 points each the concentrated fire required to take them down will be more than worth the other options.
