Ok so with the new empire book the statis of the parent block is passed on to the detachment.

There is a list that covers all of the possible ones and they range from hatred to frenzy.

One of them really caught my eye: steadfast.

Now I'm not really sure how this would work... a unit has steadfast if it has more ranks than it's opponent is does that mean:

-the detachment counts as having the same number of ranks as the parent block?
-the detachment counts as having the same number of ranks as the parent block and both are in combat?
-the detachment counts as having the same number of ranks as the parent block and both are in the same combat?

Thoughts?
