The problem is not the assault rule

1. I think I like the leader and HQs (probably even infantry company HQs, I guess) calling in arty option. Limits arty to a smaller amount of units overall, and lessens the risks of bypassing. HQs are pretty fragile, too, so they could be reduced fairly quickly. Leaders are tricky, but they are supposed to be force multipliers, right? You could even add in a limited quantity of FOs (1/company or battalion maybe depending on nationality) and retain the leader/HQ spotting as well.

I agree that leaders should be able to call in / plot artillery barrages. However, I have mixed feelings on the use of HQs as artillery spotters. As Mike notes in his post, HQs are fragile and I am very uneasy about moving such high value units close enough to the front lines to establish LOS on enemy positions!
