Wolf claw strikeforce

[Newyn]

Ur SW FaQ

Q: I have my Wolf Claw Strike Force, and I also pick a
Combined Arms Detachment. If an Independent Character from
the Combined Arms Detachment joins one of the units from the
Wolf Claw Strike Force, does he get the Counter-charge special
rule as well, or does the whole unit lose the Counter-charge
special rule because the Independent Character in question is
not part of the Wolf Claw Strike Force?
A: The attached character does not benefit, but nor
does he prevent the unit he is attached to from doing
so, provided that all models in the unit (including the
Independent Character) maintain unit coherency.

Hur fungerar det här egentligen? Har tolkat det tidigare som att de då inte får charga.
Gissar att man får göra en konga line så att IC'n också har unite coherency.
Får IC'n Pila, charge bonus och göra challange?
