M107 PF not destroying objects it detonates on

Why does the m107 PF not destroy trees and other physics objects it detonates on? How it is possible for it not to knock down a tree it explodes near with the massive explosives it carries and clear the way for the next shot. Did it not used to do this?

I’m aware 3d loss is 8x loss of force per doubling of distance but this is ridiculous. Is there a way to do physics per type of tree with different elassticity/qaulities effecting different objects. I would think it would be fantastic against house sides. Not sure which trees would and wouldn’t depending on distance. This game needs way more physics.
