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

=====Despoiler=====
*'''Rapid-Fire Battle Cannon and Heavy Stubber''' - The battle cannon is no longer the reliable MEQ-slayer it once was, and this version is no different. 72" Heavy 2D6 S8 AP-2 D1d3. It does have massive range, tied with the ironstorm missiles for the longest range weapon available to the Despoiler class, and unlike Imperials, you can take two of them for good backfield sniping. Add a carapace gun for even more ranged blasting.
**The middle cost option, at 92 points for each package.
*'''Thermal Cannon''' - What melta guns dream of being when they grow up: 36" Heavy D6 S9 AP-4 D1d6 melta. Dirt cheap at 55 points, and doesn't bring a secondary weapon with itself like the battle and gatling cannons do; it really needs to be targeting multi-wound models to make it count. Mind, you can always double up on them because god-damn that's a lot of heat. 36" range means you'll be a lot safer if you walk into half range to get that extra damage roll. Will typically evaporate whatever you're aiming at.
**The cheapest option now by a pretty significant margin. Even ranged Chaos Knights like being up close with the Iconoclast Household Ambition, so double Thermal Cannons is a pretty tempting option.
**If you're not up close, the RFBC by itself does do more A*D (this does 12.25 against a target with 6 or more wounds per model; an RFBC does 14 on average against a target with 3 or more wounds per model), albeit at slightly worse S and AP.  Up close, this scoots up to ‭15.65 A*D, on average.
**However, this weapon also has more variance than the others - your number of shots will vary more than the RFBC's do, and the Gatling Cannon doesn't vary at all; the same thing applies to the damage roll, although up close your variance is actually less than the RFBC's.  Taking these means you need to rely on volume of fire to average out your rolls to the point where you can reasonably predict what they'll do - you should always take 2 of them if you're taking any, rather than 1 and something else.
*'''Avenger Gatling Cannon and Heavy Flamer''' - The best all-rounder, albeit the most expensive at 99 all told. Heavy 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), although it has clearly been designed exclusively with GEQs in mind (S6 wounds them on 2s, and -2AP ensures they don't get a save). Tears up light vehicles and can do useful work against the heavy stuff - outshooting the RFBC even if it doesn't match the Inferno cannon. With a pair of these you will put out an ''outrageous'' 24 shots per turn - goddamn!
**Combined with Daemonic Power (Infernal Household Ambition) this is strong as fuck, but has competition now with the very efficient double Thermal Cannons.
