I've been playing some miniatures recently with the William Keyser 'Valmy to Waterloo' rules. They have a really nice feature for miniatures which is a firing template that you hold over an artillery battery's target. Anything under the template gets hit to the same effect. So, packing units together, as often happens in miniatures rules, becomes a very bad idea. Spacing them out historically is encouraged!
I'm used, in most other miniatures rules sets, to artillery fire not creating a 'beaten zone' but having pin-point accuracy and hitting only single targets, usually without depth.
I'm wondering what LG's approach is. Do batteries fire at single units (eg. a battalion)? Will another unit right behind the first feel any heat? Or does artillery fire have a beaten zone? (off to check the manual....)
