DS2 Opertunity Fire

> Another question about opportunity fire:

I've always played it so that the 'opertunity firer' gets
a shot at all of the vehicles (if desired) - after all in
'real life' the vehicles don't always have to opertunity
fire at the same time - the vehicles can fire as each
consecutive vehicle comes into view, this way the defenders formation is
irrelevent and the formation can be moved indevidually or all together as
desired (vehicles tend to follow the same path as they have to stick together
anyway).
