No one besides HoC can field HoC units. Why should Chaos Dwarfs be any different?
I agree with Thommy H.
Are you going for a record or something with all the topics started and posts without most of them being quite constructive, to be honest...
Would "Should Chaos Dwarfs be able to field Skaven units" also be a valid thread?
You could take allies for your army before 6th Edition. It was potentially fun (I'd love to be able to mix and match certain units so I could have "counts as" stuff) but too open to abuse - what's the point of a Wood Elf army with cannons?
Well then what is the point?
In a Legendary Battles game it is possible to field allies with your army, so the question is a valid one.
Also, in team games (like those outlined in the General's Compendium) it is also possible for CD to team up with other races.
I would think that for CD the obvious allies would be Ogres, Orcs & Goblins and Chaos. In my next Legendary Battles game my CD are going to be teamed up with Chaos. We saw in the SoC that they sold Hell Cannons to Archaon, so presumably they have contact with the Chaos hordes in the North, and they certainly aren't opposed to Chaos on moral or ideological grounds.
IM holding out for are new cd book!!!
i believe the question has been phrased in reverse... and should read:
"Should HoC field CDs?"... to which I'd be inclined to answer: "Yes."
But due to the way this poll is phrased I will have to abstain...
HoC includes both daemons and mortals doesn't it?

So long as the popularity of Warhammer continues, a source is needed for the Chaos Dwarf army to keep pace. Chaos Dwarfs Online provides a community with a forum for members to learn about, inform others about, contribute to, and evolve the Chaos Dwarf army in a welcoming and open minded environment. Chaos Dwarf generals, old and new, can unite under a common banner that Chaos Dwarfs Online is happy to provide.
Please be more considerate, Thommy H. Rephrase your questions and comments to try and be more polite, if you would.

ah yes...
surely we should beat this horse till it is good and dead rather than take some things for granted...
I (and I guess the original poster) meant mortals of chaos... or what are they calling them this week?
Warriors of Chaos? Chaos warriors? who knows? but surely its so goddamn important!
I think CD shouldn't be able to field any chaos units, because CD is a diffrent army it isn't a part of chaos.

So important that god decided to damn it? Metro-gnome, you use some strong words. So it must be important then if you command god to damn it! 
It just gets confusing since hordes <> mortals
I believe that Chaos Dwarves should be able to field Marauders, Minotaurs and Juggernauts (without riders).
Marauders for some reason I just really think fit well with the Chaos Dwarves (so much so that my Hobgoblins with LA, HW+S are modelled as Marauders)
Minotaurs really seem like they should be in the Chaos Dwarf army as some kind of Avatar of Hashut or something.
And Juggernauts seem mechanical and demony, and should fit with the other demony mechanical war machines Chaos Dwarves should run with.
I was wondering, if khorne, nurgle, tzeentch and slanesh all have their deamons then why doesnt hashut? Some kind of deamons made out of fire and shadow etc. I think that would be a cool addition to a chaos dwarf army.
You must have read at least one of the regular "Is Hashut a Chaos god?" threads.
Besides, they enslave all the Daemons to be used in their engines.

Of course i have but is there anything to suggest that chaos dwarfs couldnt use deamons for anything esle apart from deamon binding weapons?
Besides, they enslave all the Daemons to be used in their engines.
If they can enslave deamons to be used in their engines then surely they can enslave them to fight for them as well.
when they put the deamons in engines, then they can promis the deamons something for there work, because they can set them free after some time, but when you just let them run free across the battle field then there is a change that the deamons won't listen to you, because you have nothing to offer them.
