No one I've asked in real life can give me an answer. I don't have a decal sheet to look at right now, but they only have some of the numbers on them. There's a number 2, a number 3, I think there's a number 4. Then there's a 6, 7 and an 8. Maybe I got some of the numbers wrong, but the point is, there's clearly not a complete set of little numbers. Why not?

Perhaps they are on another sheet...? Or perhaps GW are just inept.

No it's true... The transfer sheets are terribly inadiquate... The old ones were better...

It's because chaos stole the number 5 in the last black crusade, and since they won this crusade, still maintain control of it.
