Based on a few pictures I found online, I've been able to draw up some of the insignias worn by members of the WPNLA during ceremonies. It is quite imcomplete and I have not being able to find rank name although based on some comments, the highest rank might be Brigadier General.
The rank progression style reminds me vaguely of something by I can't remember what. Any ideas ?
