Yeah, so I saw this a few months ago and did some searches for the answer but didn't find anything.
This guy at the
FLGS had some Chaos marines outside a rhino and his
HQ on a bike. The
HQ 'joined' the squad, then the squad mounted in the rhino, then they went tear-asteroiding through 'Nam. All the while the Chaos player kept saying that his biker
HQ couldn't be targeted since it joined the squad, now in the rhino.
I wasn't playing the game and didn't say anything but... really, REALLY? Is that legal?
