I have some questions concerning experience medals:1)Just how powerful are they? For instance, what is the combat effectiveness of units under the command of a general with four experience medals compared with a general with no experience medals? 2) What is the best way for a unit to get medals;a)delivering a knockout blow,b)scoring heavy losses on an opponent,c)just being involved in a lot of battles? 3)Can units receive experience in defensive situations? 4)Units sometimes lose experience when they reinforce and sometimes don't. What determines this? 5) Sometimes commanders lose experience when their units reinforce. Why, and can this be avoided?
