<p>My guess from what I've seen in the lore up to now, the Grineer ranking system is quite complex.
</p><p>Tyl Ragor for instance holds a very high influence but have no rank attached to himself, this is because he is a Grineer Scientist and not a soldier.
</p><p>Captain Vor was demoted from a very high rank(Admiral) due to his obsession with the tenno.
</p><p>there are more but...
there is the Grineer Counsil that probably report to the twin Queens and act as the official govenment for the grineer.
the ranks are most likely a remnents from the US government's millitary system where mobile troops are using the naval rankings(like Vor) and stationed troops use the "normal" ranking system.
