From what you've said my understanding is that it basically simulates a pilot approaching the combat zone, seeing a nice tasty tank and lighting it up at the maximum range it can and then 'going around' to come back to the combat zone and picking up a fresh target. And so on until the long range stuff is used up at which point it will come in close i.e. completely onto the map.
I'm in a PBEM USA vs Russia 2010 at the mo and my aircraft are currently turn a lot of his vehicles to scrap! Thanks for the tips!
