Does the regular line-of-sight rules apply to Shrouding range as well? For instance: if only two GK models in a unit are within the range rolled are they the only ones that can be fired upon and therefore possibly removed as casualties?

Yes, 40k is very repersentative like that with line of sight.

None of this fantasy rubbish where if one can see they all can.

Well, first thing hi to all, this is my first post!
I think you're wrong: night shroud cover the entire GK unit, if an enemy can 'see' a model it can 'see' the whole unit and the fire phase continues normally - that mean measuring distances from weapons and NOW can be the case where only one or two GK can be hit.

Hi Gioz, good to have you on board

With shrouding, you roll for range and lets say you get 26".

If only half the squad is inside that range then you can only shoot at half the squad as you can't see the rest of the squad because they are out of line of sight.

Well that's my take on it.

Hi!

Mmh maybe my italian version of the codex is translated not so well but it's written in terms of entire units, not models. So we play it literally: first I check the shroud to see if I can shoot the unit, then I check weapon range to see if I can hit (and what!) as normal shooting rules (and for 'normal shooting', we always play as 'check which models can be hitten' in this phase).

I hope I explained my point of view (I'm better at reading english more than writing, please excuse me if I made any mistake!)

Your English is far better than my Italian.

I've never played it as "if 1 is in then they all are in" but I will check through my codex for the wording just to make sure.

The phrase 'if the unit is within this range' is the troublesome part. Would have been so much cleaner if it had said 'the entire unit' or 'any model of that unit'.

I play it like is one in, the unit has been spotted, and so all can be hit.

Then the normal restriktions of weapon range and stuff still apply.

UK rulebook played in sweden. (i think)
