How to rebase ICBM

[gavinfly]

I want to gather all the ICBMs in the same city. But in civ4 the ICBM can't be rebased to another city. It can only stay in the city where it is built.

How can I rebase ICBM just like a missle and load them to a submarine?

I think modifying the UnitInfoXML can realise it, but I don't know which line I need to edit.

Could you give me some suggestion?

I think it's DOMAIN_IMMOBILE - maybe changing it something less, well, immobile, will help...

There are probably some other changes needed - like giving it movement point and range. Don't know off the top of my head, but comparing the XML entries from Tactical Nuke and ICBM might reveal the needed tags...

Thank you very much!
I compare ICBM with Tactical nuke XML, and find two related tags.

For ICBM
<Special>NONE</Special>
<Domain>DOMAIN_IMMOBILE</Domain>

For Tactical Nuke
<Special>SPECIALUNIT_MISSILE</Special>
<Domain>DOMAIN_AIR</Domain>

Change ICBM into DOMAIN_AIR, may let it can do the rebase mission like a plane.
Change ICBM into SPECIALUNIT_MISSILE, may let it can be cargoed like a guided missle.

That is what I think.

I can understand rebasing an ICBM since the city where it is based may come under heavy attack, but would you mind explaining the rationale behind loading a unit onto a submarine when that unit can already attack any spot on the map?

So that there is no city an attacker can hit, and thereby keep me from being able to fire that missile in retaliation on my next turn?

In case you haven't noticed, the US nuclear arsenal is divided between long-range bombers, land launch sites, and sea-based assets. The theory is that other nuclear powers probably have the exact coordinates of our missile silos dialed into their targetting systems, but they can't possibly do that with bombers and subs that aren't fixed targets. That means that, unlike the land-based nukes, we don't have to be on a hair-trigger in case we detect something that looks like it might be a nuclear attack, in a use-it-or-lose it scenario.

Things aren't quite that dire in game terms, but a mod may change that somewhat. In fact, a mod that requires nukes be rebased to a fort, cruiser, or sub before it can be used might be very interesting indeed. Having Workers be able to build a special non-exclusive improvement "Missile Silo" that allows a nuke to be based there might be very cool too. That non-exclusive characteristic more closely fits with the real world, where nuclear silos are stuck in the middle of Kansas wheat fields without affecting the ability to farm the surrounding land.

The difference is that in Reality, nukes destroy other nukes. In Civ4, nukes are nuke-immune, so it doesn't really matter.

if you do change it to domain_air, I would recommend setting its evasion_probability pretty high if not 100.

though doing that may affect SDI
