So, let us say I have 10.000 soldiers (10 regiments) in a province with supply limit 7 and attrition 5. What does exactly happen?
1) Attrition affects only the additional 3.000 soldiers?
2) Do I lose a specific and already known percent of them each month?
3) If I would have only 7.000 soldiers, would not lose ANY of them?
4) Why, if I am not at war, for example, I can keep like 18.000 soldiers in a single province of mine without losing not even one of them?
5) So the relationship between them it's like attrition shows how much do you lose when you get over the supply limit, right? That's all I have to know about them?
1) You might say that, bacause attrition won't kill more than 3000 soldiers.
2) You said attrition is 5, which means 5% of the army will die. BUT in the same time they get replenished from your manpower pool, so if the attrition number is green you will actually replenish more soldiers then attrition will kill. If it's orange, the number will stay the same, and if it's red you will lose more then you replenish. So you can't know exactly how much will you gain/lose in the green/red scenarios. Note that attrition will instantly kill the exact percentage shown when you enter the province bacause replenishment is done only at the beginning of the month.
3) True dat.
4) Because replenishment rate is much higher in your home provinces, so you replenish faster than attrition kills (but this can drain your manpower pool so don't do it)
5) I don't quite catch what you mean, but i think you're right
