Editing Warhammer 40,000/8th Edition Tactics/Genestealer Cults (section)

===Fast Attack===

*'''Cult Scout [[Sentinel]]s''': Identical to the Imperial Guard version. Except we pay 3pts more for HK missiles, autocannons and 2 more for Heavy flamers than the IG, even though we basically are the IG. Guess lack of proper Mechanicus support hurts. Since they are {{W40Kkeyword|Brood Brothers}}, they can not benefit from a Jackal Alphus for example.
*'''Cult Armoured [[Sentinel]]s''': As above, identical to the IG version save for Keywords.
*'''[[Atalan Jackal]]s:''' SP 14" with cult ambush and a variety of CC and ranged weapons. Enemy units targeting them suffer a -1 to hit to shooting and the bikers have 2 wounds each (4 wounds on the optional quad bikes), which adds up to be a very solid defensive profile, especially with the improved save from the Rusted Claw Creed.  The quad can choose to take a heavy stubber, an atalan incinerator (12” heavy flamer), or a mining laser (24” LASCANNON). Jackals function as either fast, cheap melee threat, or much needed fire support. The fire support role is greatly improved by a Jackal Alphus, who can affect them from up to 12” away. The biker doctrine (Rusted Claw) also improves the ability of fire support with the no-penalty-to-moving heavy weapons, and the move-shoot-move stratagem. However, the incinerator flamer option for quads means that they can be equally effective at close range fire support without such additions. Neither of these are necessarily bad choices. Alternatively, any cult type can use them as a cheap, fast and fairly accurate delivery system for demo charges. 
**Since there's no limit to the number of Demo Charges the unit can take, a Rusted Claw unit with 5 demo charges can make for a really solid mini-nuke (once upon a time 75pts. Now under CA19 it's 100). It'll cost a couple of CP, but with a Jackal Alphus buff and '''Drive by Demolitions''' + '''Extra Explosives''', you'll be throwing 5d6 shots that hit on 2s and wound a knight on 3s.  Anything without a decent invul save will likely be reduced to a pile of used car parts.  And afterwards you can zip around and continue being a nuisance until your opponent decides enough is enough. 
*'''[[Achilles Ridgerunner]]''' -  Mv 14”, Scout move, 2 heavy stubbers and a choice of heavy mining laser, missile launcher or heavy mortar. Also gets the options of either +6" to all ranged weapons or ignores cover with its weapons. Flexible and fragile. Take 2 so you get the most out of their options. Heavy mining laser weapon option has D3 shots, which helps offset the average BS skill. Shorter ranged than a lascannon, the spotter wargear choice can fix some of that if desired. While the heavy mortar option is unimpressive, assuming that you ignore the indirect fire and still use its heavy stubbers, it may be better at clearing chaff compared to its other options for a cheaper overall cost. It’s overcosted as only an indirect fire unit, with Brood Brother mortar teams serving that role better. No matter what the optional weapon is, the Ridgerunner needs to use all its guns. Despite the Ridgerunner’s fast speed, it prefers not to move due to carrying heavy weapons. However if a desired target moves behind sight blocking cover, moving a good 14” and hitting at a penalty is better than maybe not being able to hit at all. The Ridgerunner is fragile, so it really relies on scout move or cult ambush to set up in the best possible position (I would disagree; please see 3rd bullet point)
**With a huge point drop in CA 2019,  this unit has quickly become a solid contender for dedicated anti-tank duty; especially after the point increase to demo-charges.  When equipped with the Heavy Mining Laser, they're now only 9 points more than a lascannon Sentinel.  Meaning it's much more feasible to run a fleet of 3 or more of these guys and escort them with a Jackal Alphus for that juicy +1 to hit.   Not many armies can spam mobile lascannon shots as cheap and efficiently as Ridgerunners, so it's definitely an element of the army worth exploring.
