grenades and wood wall

Does anyone know exactly how many it takes to take down a wall?

It used to take 7 well placed nades to take down a wall, but since they made changes to them it’s really hard to tell.

I threw 17 at a wall and it ended up blowing a wall on the other side of the room…

And what about doors? any idea how many?

Around 15.

For none decayed walls around 15 nades and for a metal door around 9 nades. The key is to drop the nade as close to the desired target as possible and not have it roll away. They reduced the area of effect, so its best to try to be as accurate as possible.
I am just going to leave this here.
