The problem is not the assault rule

[FM WarB]

A fascinating thread, and I hope some change to artillery spotting is made. By keeping chain of command in mind, inter unit boundaries will be more important. I am not sure if it can be done with forward observers or commanders or some combination, but here is an idea.

platoon unit:
spots for indirect fire units belonging to its own company only

with C&C on, company command unit (or 1st platoon):
spots for indirect fire units belonging to its own company + one command level higher

Commander 1 or FO 1:
spots for indirect fire units belonging to its own organization + one command level higher

Commander 2 or FO 2:
spots for indirect fire units belonging to its own organization + two command levels higher
etc, etc, etc.

Only five levels are needed for a Commander or FO placed at company level to call all the way up to army level.

Using different combination of numbers of commanders and FOs, their levels, and who they are attached to (including firing batteries), it would be possible to simulate different armies' artillery tactics and capabilities.

AND make this an Optional Rule, pretty please!
