Which shell to use

Hambijon: I've got some lucky shots knocking out all of their tires on one side when they lined up perfectly. If they are crossing horizontal to me, I tend to shoot lower to over-pen to the tires on the opposite side. Slowing them down drastically or stopping them completely is pretty much a death sentence for them.   In reference to the shell type, I generally use AP but if I see a wheeled tank on the other side pre-battle I'll prep an HE shell if I'm able.  All depends on the light tank being used, like the others said.
