The West Papuan National Liberation Army is a militant organisation seeking the independence of West Papua from Indonesia.
The WPNLA fights will limited economical means and as such while on operation, individual tend to wear what ever combination of military and civilian clothes they can get access to. During ceremonies and where the WPNLA operates more openly, members do tend to adopt a more uniformed look which includes insignias. Rank appears to be indicated by hard shoulders boards. Note that the top circle is not a button but is flat and it as well as the chevrons and stars appear to be painted directly onto the board.
The following are based on photographies taken during a ceremony in 2010 and the list is more then likely incomplete.Pictures taken around 2015 appear to show a change in insignias with the chevrons being replaced with bars.
