Artillery overload

[SFTOM@1]

I understand the concept of art. overload: depending on mission type you may purchase x% of your total force value without penalty...Right? I can't find where x is defined. Are art FO unit(s) cost included with art unit(s)cost in determining total spent on artillery. I would like to see eg ASSULT=15% limit ADVANCE=12% MEET=10% etc.Hope you are feeling well,thanks in advance for any info. I would urge anyone who enjoys this game to get the CD version...it's well worth the cost.
