Some units in various army lists, such as the Empire Steam Tank or Dark Elf Hydra and Cold Ones say they cannot be brigaded with certain other units.
In game terms, what does this actually mean?
Is it for example;
a) such units cannot be ordered as part of a brigade including other prohibited units in the movement phase.
b) such units cannot even be placed in base contact with prohibited units.
c) something else?
I favour option a) as the brigade rule only applies when ordering units as a group, it says nothing about placement of units together. However there could be some argument to say that such units cannot ever be in contact with prohibited units to form a single battle line.
Advice and thoughts welcome
