The problem is not the assault rule

[umbro]

The problem there is this thread started as a means to reduce the effectiveness of units bypassed due to the extreme assault rules in calling in arty. If every regular infantry unit (would this include SMG and engineer platoons) is an arty spotter, then you're right back where we started.

I thought that the issue was that any arty could be called upon to support any unit.

If the issue is bypassed elements then you could use whether they are in supply range of an HQ as a determiner. But then how would you deal with cut off units with radios?

It seems that if the any arty/any unit problem were addressed the other issue that you raise would be ameliorated somewhat.
