How close do you let your tanks get?

I used 80m, what did you chose?

I rather use 60 m

Using 80m but noticing that sometimes if i am too close the enemy tanks wont fire and i cant hit the enemy tanks.
I have a feeling this is more to do with clamping my viewport earlier in the section so will have to sort out the -vertical pitch on my clamp so it can aim down more and get the collider. (At least thats what i think it is at this stage not tested yet)
