AoS Firelance rules

[Audvin]

If you have both a Scar Vet on CO and a Scar Vet on Carno in a Firelance and the one on Carno is the General. Will the Azyrite Hunters ability effect Knights in proximity to either of them or only the General?

 

[Aginor]

You can only use one Scar Veteran as the leader of the Firelance Starhost.

 

[Killer Angel]

If you have both a Scar Vet on CO and a Scar Vet on Carno in a Firelance and the one on Carno is the General.

Minor nitpicking: The leader of the Starhost is not automatically the general of the army. I take you are meaning that the ScarVet on Carno is the leader of the Starhost.
That said, Aginor's answer is correct

 

[Audvin]

Yes I was thinking of you bring an extra scar Vet. But it makes sense sinne he is not a part of the Starhost.

 

[Killer Angel]

Yes I was thinking of you bring an extra scar Vet.

You can still bring one and use the command ability for additional attacks and rerolls, even if she's not part of the starhost
