Fire at first vehicle in a convoy? Or last?

The_Chieftain: Do both. If you're a tank on your own, you're probably doing something wrong to begin with. You're supposed to be engaging as a platoon, or at the very least, a section. That means that you can start on both ends, and work inwards.  Or, if you're a platoon, two tanks start on the ends, two tanks start in the middle, and they work towards each other.
