Huge improvement. Good job!
Let me get a bit more detailed about this whole hit boxes/destructable environment thingy.
You have to adjust the collision as mentioned before. Make it rather a bit smaller (not filling out the whole object). The player will get stuck and wont alsways understand why he/she got stuck.
Rather something like the red circle and not the current yellow:

Destructable environment: Let's take a look.
You have to be more consistent in what is an obstable and what not.
See the small bush with the question mark? Why cant i cross it while i can cross the medium rocks in green dotted circle).
Expecially while driving a tank. This is not logical.
I would also let allow the player to shoot a tree to have it burn down.
Let me know if you need help how to do it. It is very simple.
Cheers!
