Garrison/City Defence questions?

[clinton]

Is this how garrison works:

(1) Garrison units increases city strength, which increases ranged attack power. Garrisoning a warrior in a city will help ranged attack power more than an archer.
(2) Garrison is instant, and doesn't build up over time? If I'm planning on doing a ranged attack with the city, I should do this before the garrisoned unit moves.
(3) Does the increase in city strength depend on the health of the garrisoned unit?
(4) Lets say the city gets damaged with a unit in garrison, what happens when the garrisoned unit leaves? Say the garrisoned unit is providing half the strength, and the city has taken half damage, if it leaves does this mean the city is down to 0 strength immediately?

If people could clarify what I've got right and wrong here it would be appreciated.

1. Yes, but using the archer will allow you to attack with both the boosted city attack and the archer. This will however leave it with a lower combat strength during the hostile turn so it takes more damage when they attack it, and you do less damage to them if the attack was melee.
2. Yes.
3. 95% sure that it doesn't.
4. No. The garrison raise the combat strength, making it take less damage. It doesn't increase the hitpoints though, so lowering the combat strength again has no effect on the health.

A garrisoned unit gives I think 25% of it's melee combat strength to a city; unit health does not matter. (2) is correct. If the unit leaves, the city hitpoints remain the same, it will just have less combat strength in the next battles and therefore eventually take more damage than it did with the garrisoned unit.
So you got combat strength and hitpoints mixed up. They are two separate things which have no influence on a cities actual damage dealing capacities - damaged units however deal less damage (have yet to find out by what formula/percentage).

There is a policy Tradition:Oligarchy which gives the city 100% more ranged strength with a garrison.
