They can be pictures from the Yugoslavian Civil War, or pictures of any Yugoslavian rifle in use anywhere in the world.
The Iraqi Tabuk will also qualify since the factory was set up by Zastava for the Iraqi's and they are just about dead ringers for the Yugoslavian rifles.
Found this somewhere online.
Former NYPD Commisioner in Iraq. His body guards are supposedly South African PMC's.
I can't tell if they are Tabuks or Yugo rifles.
