112 * if there are no military in the sector, che recruit from
113 * populace if pop loyalty is > 10. They spread subversion otherwise,
114 * trying to lower pop loyalty.
115 * if che outnumber military, they stay and shoot it out, kill the
117 * if che are outnumbered by less than 5 to 1, they blow up stuff,
118 * killing innocent civilians (never uw's) and damaging commodities.
119 * if che are outnumbered by more than 5 to 1, they try to leave the
120 * sector for a nearby sector with fewer military.
122 * if the military lose any attacks, the pop loyalty in the sector
123 * gets worse, representing military defeat.
124 * military can "catch" che's after bombing attacks, or after they move.
125 * If military catch them, then they get to shoot it out with a portion
126 * of the che's depending on the # of mil in the sector. Chance to contact
127 * is around 10% per every equal number of mil:che ratio in the sector.
128 * "contact" is by 20% of the military in the sector, and odds are equal.
130 * Without a doubt this routine should be broken up, if only for readabilty.
