a4phantom said:Is this correct:
A city gains a defensive bonus from culture.
A city also gains a defensive bonus from walls and castles.
Only one of these, the higher, apply to any given battle (and is presumably the one shown on the map).
Walls and castles do not add to defense against gunpowder units (but do against cavalry and tanks).
Assuming I have all that straight, when I am shelling a city with bombard is it taking down both the culture and wall defensive bonus? I just see "defense reduced to 23%". Sorry if that's badly put, I'm tired.
All correct.
a4phantom said:2. How does unit maintainance work? In Civ3 you were allowed a certain number of units per city, altered by the size of the city and your government type. For every unit above that, you had to pay gpt. How does it work in Civ4?
In Civ4 there's a number of free units dependent on the total size of your population (the sum of all your city sizes), it's called free support in the financial advisor (F2) if you mouse over the unit cost. The vassalage civic increases the free unit support. The pacifism civic causes an extra unit support called military unit support.
More about the subject can be found here.
a4phantom said:How does collateral damage get applied? If the unit defending my stack against the suicide cat beats it handily, will other units still get damaged? If the defending unit has first strike?
Collateral damage is always applied to the stack, totally independent of the way the battle with the main defender develops. Collateral damage is applied to the defenders other than the main defender. The number of collateral damage hits is determined by the number of defenders and the type of unit doing the collateral damage (5 units get more damage in total than 2, an artillery hits more units than a catapult). The damage the collateral damage unit does is dependent on the current strength value of the collateral damage unit and the basic strength value (without compensation for hitpoints and defensive bonuses). The damage output is modified by the barrage promotion. Collateral damage can only reduce the strength of the defenders to a certain point, 50 hitpoints for catapults, 30 hitpoints for artillery.
You can read more about collateral damage in the collateral damage section of this strategy article.
A few points on when to use it:
You should use it against stacks of strong units (for instance those defending a city). It will reduce the hitpoints of many units and then they will be much easier to defeat for your other units. A reduction in hitpoints reduces the damage a unit does in each combat round, it reduces the chance it wins a combat round and the wounded unit cannot sustain as much damage before it dies.
You should not use it against a stack that only has one strong unit. The unit will not do collateral damage against the strong unit because it will fight against that unit. It will weaken the other units in the stack that you could already beat (this assumes that you have enough units to defeat the weak units).
You should use it to reduce defensive bonuses from cities.
Different people have different ideas about when a stack is weakened enough to be defeated with normal units. I read reports about people using massive amounts of artillery and losing them en masse to weaken the enemy. I myself use them somewhat more sparingly. I have some dedicated city attackers and use artillery type units when I think I might lose some of these city attackers. But if the city attackers don't need the help of collateral damage, then I don't use it.
