Activating Kommisars...6.6

[cjsiam]

In the rules Commisars are called out as Not behaving as leaders....

But the rules then go on to say "Kommisars are activated individually and never affected by other leaders"

So there are two things that leaders can do
1) Activate units
2) help with morale

Are Kommisars meant to NOT be impacted by either or just 2) morale?

How can I activate them?

1) they can self activate---that is clear
2) Can They be activated as part of a stack? the rules say "activated individually" --- if they are in a stack which activates--do they activate?
3) Can They be activated by an Leader as part of a group activation? ( I think no---but not sure)

IF they can only activate as a single unit---and you are in a FOW scenario with lots of units....they won't be moving much...
