Stupid units rule states that:

"Certain units are not noted for their intelligence and must receive direction from someone else. If there is no one to give them orders, roll a D6: 1-2 the unit has Advance Orders, 3+ Charge Orders."

Can any unit give them orders or does it need to be a unit with Command or HQ abilities? How close to they need to be to give orders to the stupid unit? 10cm?

That's good, but how close to they need to be to give the orders?

Sorry, I am in a very quizzical mood at the moment!

Probably varies by army listing. Offhand, the only army that I can think of with a model with that ability is Chaos and that model is the Chaos Troll. The Troll Warband comes with an Aspiring Champion and 10 Trolls. Presumably, so long as the Aspiring Champion is alive, the Stupidity roll is not made, and it is likely this that the rule is referring to. My guess would be that the Core Rules were finished before the army books were, and thus it wasn't certain that this would be the case, thus the wording in Core being vague.

If this is the case, I would recommend that either the wording in Core be changed to reflect this or it be removed from Core entirely and put in the Special Rules section of the Chaos pdf with such wording.

Good catch Bissler.

I too was struggling to think of an example other than Chaos Trolls (one of my favourite units incidentally). I agree that it makes sense to remove this rule from the core rules if it only affects one or two specific units. The Chaos rules describe how to handle Trolls, so the core rulebook doesn't need to.

Special rules which apply to units across different armies are logical to have in the core rules. It's just special rules which only apply to one or two units, or to a specific army, which really don't need to be written out in the core rules in my opinion.
