The armoured anti-riot vehicles have a capacity of 10,000 liters to shoot cold and hot water, and three 100 liter tanks to shoot burning chemical liquids. The water is mixed with paint or tear gas that cannot be washed away. Each vehicle has two guns for shooting liquid up to a distance of 70 meters- it is controlled from inside the cabin. The price tag for each unit is 650,000 dollars. Also, a lot of extra burning liquid, paint, and tear gas was purchased.

From the LA Times

An opposition news website is reporting that Iran has imported high-tech armored anti-riot vehicles equipped with water cannons that can douse people with boiling water or teargas. The website said the vehicles were a rush order from their manufacturers in China, Dalian Eagle-Sky. With an alleged price of $650,000 a unit, the 25-ton trucks each hold 2,640 gallons of water, which can shoot hot or cold water at a distance of up 220 feet. They can also shoot tear gas, burning chemicals or paint stored in three 26-gallon containers. It includes a plow, which can presumably demolish makeshift barriers placed on streets by protesters, or even the demonstrators themselves.
