I was reading from an earlier thread about a thunder 1 and 2 Iran had, the 1 was 9 miles distance and the 2 was (i believe) 43 miles. They were mobile guns, similar to cannons or howitzers.
CNN reporter just said haifi is 40 km away from border..plus add on a few KM since they likley didnt fire right at the border
I don't know if this is the same, but they are Iranian:
One of the Iranian military's greatest threats are its self-propelled howitzers. The Shahid Industrial Complex manufactures two models of self-propelled howitzer, a 36 tonne 155mm, and a 17.5 tonne 122 mm. All parts of these weapon systems are locally produced using Iranian steel including their 850 horsepower diesel engines and their 8 gear transmissions. The 155 mm “Thunder 2” self-propelled howitzer has inch-thick welded steel armour requiring a near direct hit to destroy it. The Thunder 2 can travel at 65 kph with a range of 450 km and can fire four, several-pound, rocket-assist high explosive projectiles per minute to a distance of 30 km. The Thunder 2 is a knock-off of the American (United Defense Industries) M109 of which 440 were sold to the Shah, many still operational.
The Thunder 2 has been in quantity production for several years. The self-propelled fleet is supplemented by a large number of towed howitzers, both 155 mm and 122 mm, manufactured by Hadid Armament Industries Group. These weapons are towed into battle by 6 x 6 ten tonne trucks which can also carry substantial amounts of ammunition.
