No, it is for PLZ-07 122mm SP Howitzer. It can also supply ammo for PLZ-10 120mm SP Mortar-Howitzer, but with a different ammo rack.I think that's the ammo resupply vehicle for the ZTL-11 and perhaps also the 8x8 self-propelled howitzers. The 8x8 wheeled armor brigades have logistics vehicles based on the same 8x8 chassis as the rest of their fleet.
Well to be fair almost every advanced powers out there has put some kind of very accurate guidance methods onto their rockets. Only second rate and third rate countries that cant afford them solely stick to unguided rockets.Currently only China is using rockets with the accuracy of cruise missiles.
