Russian artillery units operating BM-21 Grad multiple launch rocket systems have started filling the weapon's guides with expanded clay aggregate or sand. This technique has become widespread among the military.
Senior battery officer Semyon Efimov explained that this measure reduces the risk of detonation of the main ammunition package even if a drone hits the upper part of the combat vehicle.
We cover the top two rows and fill them with sand or expanded clay aggregate. The chance of the bottom row detonating becomes much lower, even if a "bird" hits from above.
Apparently, the guides are then cleaned, and a shot is fired. But Efimov did not explain this part.
Recall that the Grad carries 40 guides for 122 mm rockets. The firing range of a high-explosive fragmentation projectile is 40 km. The MLRS combat vehicle is built on the Ural-4320 truck chassis.
