According to the award system in game.
The ranking structure should be like this
CO>ERT>Commander>Inspector>Deputy Warden>Warden
But when it comes to the rank insignia
Commander has 3 stripes and a star on top
How come Inspector has only 3 stripes when Inspector is the higher rank?
Therefore, I suggest to move Inspector a lower rank, whilst commander should be the higher rank. Or to swap their rank insignia.
