Yep.
Take 2 Kastelan units, just to be safe, and kit them out entirely with phosphor, and then give the Kataphrons Grav cannons and Flamers.
I won with an 800 points Elim Manip against 1250 of Tau, and that only had 10 Firewarriors. All the rest was mech suit jobbies, including a Riptide and Stormsurge legs.
And having said that, it was actually just a 3-man Destroyer squad, behind a pipe, supported by the 2 robot units. The other Destroyers were on the other side of the table with the Firewarriors.
But woe is ye who suffers the opponent that knows to shoot the Kataphrons first. Took my opponent 4 turns to start shooting them, but once he did, they dropped fast. I actually had to resort to sitting my last Kataphron right behind one of my Datasmiths with the Stasis field.
(That's actually a really effective cover tactic, as it turns out.
)
What I suggest is, given you can easily get a solid Elim Manip for 800, is fill the remaining 200 with 2 completely vanilla 10-man Vanguard squads, and use them as bubble wrap, but also as a swift way to deal with light armour, should you need that.
(I did; got tied up with those ruddy Firewarriors for 3 turns)
Not to mention they're also damn good at taking down
MC's, like the Kataphrons. Like Cinnamon and Nutmeg.
There's also the whole "Mind games" hilarity to use against infantry-heavy armies, simply by using Eradication Beamers and Vanguard.
They'll want to get closer to the Dunecrawlers to avoid the huge pie plates, but as they do so, risk getting into range of the Rad Carbines.
I find this to be a very effective way of splitting Infrantry from their vehicles, which is an absolute MUST when using Kataphron Breachers.
And one can also accertain a strong cheddar with devilish objective marker placements, and a Holy Requisitioner.
Nothing irks Ravenwings and DEldar more than having these guys grab onto the back of their hovercraft, and proceed to puncture the fuel pipes with uncanny ease.
But nothing irks Kataphrons more than masses of shots headed their way, hence the Skitarii trick ^.
(Seriously, these guys are squishier than I'd like. The lack of anything other than an Armour save feels so weird when everything else I use has FNP.)
