Disableing Tanks

[Tirak]

I'm wondering if anyone's got a good explanation on how this system works, because it seems very random. On Basrah I've seen tanks near full health lose turrets and thrown tracks, on Kashan and Al Karuf I've seen tanks with almost no health remaining rumble back to base with no ammunition and in relativly good shape. Is it sensitive to where you've hit the tank, or is it just random every time the tank takes damage?

This is just random

It is a bit random, because of a bug in BF2 which means it's not always possible for us to read or set vehicle damage.
