What's the order of rallying?

[dTerm]

I'm sorry, but I have to bring it up again.
I did some more rallying in different company/platoon structures and there are some things left, which irritate me.

- So apparently A0 can never rally a unit under a company hq, only units in platoons directly under his command.

- The first one attempting to rally a unit is it's platoon leader, next the company commander (or A0 as above).

- The leader of the squad/section itself is always the last one trying to rally his unit.

So the sequence of rallying attempts would be:

1) platoon leader
2) company hq OR overall commander (never both)
3) squad leader

Is this correct? I'm not asking to complain, just to understand, because in the manual it's says otherwise. And it's not, what I did believe is the case until now.
