   More of JDB works in Ukraine. First one is classical Syrian-styled trucknical with 57 mm caliber autocannon (S-60) and second one is Russian truck with parts of MT-LB used as add-on armor. Inshallah, soon they will get to Toyotas with BMP-1 turrets and VBIEDs.

I'd wager that this is more effective against HEAT than sheet metal bolted on the side. "Rocks" are a medium with a potentially complex microstructure and composition. It could get even better if they have enough space to jiggle a bit when hit.

FYI, granite has good properties against shaped charges. ;)

 

Not really good according to trials conducted in Sweden during the 1950s. The possible weight reduction was judged to be some 25%; up to 50% was achieved in tests with non-practical armor. So a lot of granite is needed to provide protection even against small shaped charges. The performance is worse than that of glass armor.

I've made an error of writing :

 

According to the ETCA (Etablissement Technique Central de l'armement d'Arcueil ; Central Technical Establishment of Weapons at Arcueil) Pyrex glass had good properties against shaped charge warheads while granite was effective against APFSDS.
