Recently ive been playing the 2s25(m) a lot and discovered that anytime you get hit the enemy shells spall more than ivr ever seen any vehicle do,considering the 2s25 only has about 10-30mm effective armor i find it weird that it spalls so much. Even if you get hit in the last bit of the tabk your crew WILL die no matter what and no its not my crew its maxed+ aced. And as we know there can only be so much spalling as there is mass ( armor) and so much spalling i think isnt even possible for so thin armor
