I don't understand. Why Iran is funding on barreled artillery systems while it can produce rocket artillery with less price? They have good upgrades of katyusha like Fajr 5 or Shaheen 2. And they are not funding much on armored vehicles nowadays. Are they repainting and showing their Raad 2 in parades each year?
Tube artillery are area saturation weapons, they don't have the accuracy or the ammunition load to provide sustainable pinpoint fire.
I'm not sure if they're repainting them, but at least some of them have been displayed in unit colors along with other armor from that unit, so i don't think they're just
repainting them like with the Zulfiqar or something.
