BZ2 Feature Request: Target From Maximum Distance

[bornlibra23]

In single player games units like assault tanks & other heavy units target a unit from maximum distance they can. However units like the Sabre go very close to the buildings especially gun towers to attack them. Is it possible to have units engage the targets especially buildings like gun towers from the maximum distance?

BlastDist = * // The distance from which a unit will fire its weapons.

These are less feature requests and more "how do I?".
