I seem to remember reading that the more units in a hex, the greater the chance of ONE of them getting hit by shell fragments. Also you can damage your own unit by same hex combat with grenades, HEAT rounds from AT weapons, etc. So there is at least one subroutine that "looks" at unit density in a hex. You might want to try that. Set up a test and buy 100 snipers, put them in a hex, if you can and then direct fire a 100mm shell into that hex. Then run and hide before the UN shows up with a war crimes warrant.
