19. Morale on the field of battle. There are morale penalties assessed to units when nearby friendly units rout. Any idea what "nearby" means, distance-wise? The penalties assessed for unit casualties, are those applied based on the full-strength size of the unit, or what they go into battle with?
Hmmm, "nearby" I'm not sure on, I've never really got to grips with distance conversions, but I expect it would be similar in range to the general-proximity morale bonus, but that's just a guess....

I believe the unit-casualty morale loss is based on full-size units, but I could be wrong. There are complicating factors eg smaller (diminished) units -- statistically speaking -- are more likely to have higher valour which slightly offsets morale effects, and I expect it also skews the "outnumbered by enemy" morale hit as well, as a smaller unit is more outnumbered.
