No Tank Leaders

[Shad]

Oh yeah, I forgot about that. So then, each AFV gets a leader and cannot be activated by another tank leader unless in the same stack. Correct?

Not completely---each tank has a leader---each tank leader can activate the hexes adjacent to him, and his own.....a special case where 
leaders of "equivalent" rank can be activated.....they cannot impact other types of units though....(there are some exceptions---look where peter indicated)

I don't think you can chain---like with multiple level infantry, but a 7hex of tank stacks can all activate at once....

Rule 6.8 - inherent tank leader

Rule 6.81 - they can activate tanks in the 6 adjacent hexes

Rule 6.82 - they cannot chain activate beyond the 6 adjacent hexes
