Editing Warhammer 40,000/8th Edition Tactics/Imperial Knights (section)

====Auto Weapons====
*'''Rapid-Fire Battle Cannon''': The battle cannon is no longer the reliable MEQ-slayer it once was. While it does have massive 72" range, if you're sitting back and sniping you're not really getting the best out of your knight. Overall, excels at very little (it has a marginal advantage over the other weapons against T7 vehicles due to the wound math).
**Take one if you want more dakka on the Crusader, and it's still okay at dealing with medium vehicles, just don't expect it to be as good as it was in 7th.
**With {{W40Kkeyword|House Raven}} the RFBC has an effective range of 87" (with no movement penalties), easily capable of hitting anything ''anywhere'' on the board. 
**A good tactic would be to fire the RFBC last; 72" is long enough to reach almost anywhere on the board and it's pretty difficult to hide from a Knight. If your dice get cold and your other knights leave some stragglers, you can use the cannon(s) to clean up.
**Don't underestimate the battle cannon in 8th. It's combination of multiple shots, S8, decent AP (-2) and multiple damage (Dd3) means that it will perform reliably, if not spectacularly, against just about everything in the game. 
*'''Armiger Autocannon''': Unique to the Armiger Helverin, 60" Heavy 2D3, S7, AP-1, 3 damage. In addition, the weapon ignores the penalty for moving and shooting heavy weapons. It will have difficulty against the T8 fatties (Land Raiders, Leman Russ', Wraithknights) and 3+ saves mean quantity is vital, but the Helverin mounts two of them. Fantastic for how cheap a platform it is mounted on, it will do work for you.
**The most efficient weapon you have for taking out Guilliman; you hit and wound on 3+ with 4d3 attacks, the AP knocks him down to a 3+ save, and damage 3 means he'll go down quick. All of this means that you “only” need 20.25 shots from this gun to take him down, and for Guillimans price you can buy two Armigers which can pump out an average of 16 of these shots a turn (although this doesn’t take into account his regeneration ability or the fact he’ll be hiding behind meat shields).
*'''Avenger Gatling Cannon''':The best all-rounder, and now cheaper than the RFBC even after including the mandatory heavy flamer! 12 S6/AP-2/D2 is the absolute champ against all kinds of infantry, including TEQ (that 2 damage in particular will make Primaris marines and the like cry). Tears up light vehicles and can do useful work against the heavy stuff - out-shooting the RFBC even if it doesn't match the Inferno cannon.
**Always a good idea to pair with a Thermal Cannon on a Crusader Knight, as they share the same range and complement each other pretty well.
