So me and a friend ran into quite an interesting dilemma the other day.
I was playing Orks, and he was Space Marines. I have a Ork Battlefortress(Super-Heavy Vehicle) and I loaded it with 2 squads of 10 Lootas and 3 meks, My Warboss, Big Mek, and 2 separate Meks. The idea be that the Big Mek was provided a Kustom Force Field(from the Waaagh Gaz book, also yes I was using the books detachment)
and we ran into an interesting scenario. I generally use the Battlefortress to Thunderblitz units.
I decided to try my hand at running down a Dreadnought and his buddies. Unfortunately I failed at such. His next turn, he got his dreadnoughts in range to hit the battlefortress with their Heavy Flamers(there were 2 flamers) The issue that arose was there was 30 orks in the battlefortress, it is opentopped, and we were not sure how the No Escape would affect all the units inside(technically being 6 separate units) Would the Flamers hit all the units, or do all the orks count as one unit inside the tank?
Also would the KFF save be allowed against these hits, as its not technically hitting the vehicle, but the orks inside?
I didn't find the right solution from the Internet.
