I have a question concerning the Squad Mode Ability stated in the title.
As the rules state, Chapter Squad Mode Abilities can only be used and taken benefit of by members of the specific Chapter. (With the exception, that a Tactical Marine has taken the 'Tactical Expertise' Ability)
Now the 'Lead by Example' Chapter Attack Pattern specifically states that 'all Battle-Brothers in Support Range' benefit from it, where the others just state 'Battle-Brothers in Support Range'. Does this indicate a different handling of this particular Squad Mode Ability?
Example: A Space Marine from the Ultramarines Chapter, who will be able to use this ability, as it is an Ultramarines Chapter Ability, is in Squad Mode and decides to use this ability. He will now gain a bonus equal to his fellowship bonus to all tests. There are two more members of his Kill-Team within support range, but they are from a different Chapter. Is this Ability now handled differently and they can benefit from it?
I thought it might make sense with the pretext of the ability stating: " Off all Chapters, the Ultramarines pride themselves as among the most loyal and bravest of all the Emperor's chosen, a fact that they like to impress upon their fellow Battle-Brothers."
I guess in general I am wondering about the usefulness of Chapter Squad Mode Abilities if there is no Tactical Marine present with 'Tactical Expertise'. I understand that it is desired to have a Kill-Team made up of different Chapters, because it is one important part of the role playing that the characters can grow together and form a team, even overcoming Chapter rivalries and so on. But if you have a Kill-Team in which no Chapter is ever present twice than only the player from the given Chapter might ever benefit from the Chapter Squad-Mode Abilities and it might as well be a Solo-Mode Ability, or am I missing something?
