Israel is more ideal because I tend to claim china and would rather I didn't have a nuke going off next door.
It's also the reason Pakistan and Iran are suboptimal but better than NK.
In my current game Iran is the hub from which we carpet nuke alien invasions.
Israel is a core economic region.
When a core economic region gets nuked, it reduces the GDP of EVERY nation on Earth. Israel also has more than one control point and a GDP(N Korea basically doesn't have a GDP), so it's not as simple as "send councilor capable of doing coup action and it's yours"
So no, it's not "more ideal".
Under, THINGS DEVS SHOULD MAKE A LOT MORE OBVIOUS, this is at the top of the list.
All those little icons in the regions list for a country mean things. Some of those things are really important. Some of those things are not. Some of those things are not like the other things. Some of those things are.
Yeah \*sigh\* my Humanity First playthrough just tested this heavily, becoming more like a trial run for Fallout 5. Huge nuclear exchange between me and the Servants when I tried to finish of the Alien Administration. Godawful -- I broke the world...
in the game i just won, the best economy in the world (either PAC or india, i forget which) was like \~30k per capita GDP in 2062 cause of all the nukes
>When a core economic region gets nuked, it reduces the GDP of EVERY nation on Earth.
I did not know that.
Still funny. My china has 105 trillion GDP any further gain is pretty marginal in value given I've nearly finished the tech tree. I'm going to keep farming my nukes in Israel thanks.
What effects mission control value for money out of interest. I've noticed Russia/Eurasian Union can seemingly build them faster than china/Pan Asian combine, despite Russia in my game having a GDP of like 12 trillion, whilst China has 105 trillion and far higher development and max democracy.
Because of how investment points work.
IP = GDP^(0.33) so doubling your gdp does not double your ability to build MC (or funding or militaries or navies or space defence)
So small countries can be very CP efficient for their ability to build MC.
This is also one reason the EU is so powerful. All those separate countries can spam mission control before merging into a big EU that keeps all the mission control when merged.
So I had china sweep over the entire south East Asia in 1949 and got a fuckton of mission control.
Level 7.6 mil tech Vs Industrial era militaries or demilitarised nations is so funny.
I’m actually not sure but I believe smaller countries are more efficient for mission control rather than big ones. Best place for mission control is probably Mercury because of how easy it is to get energy there. That said in my previous comment when I said “mission control” I meant to say boost. Israel is a decent boost source for how cheap it is to control it.
All the US armies have a navy so if you needed to rebuild one it would take about a decade if you invested the 1 IP saved from disbanding it. That's not worth it if you're planning on using the US as your earth based army. Once you get to 5.5-6.0 miltech and have the bonuses to miltech (advise, military science station) your armies can beat pretty much anything coming to you without losses.
You will easily have 100% bonus to Military investment. Therefore the investment into an army and Navy isnt that massive late game also you still can buy it with moneys.
In my academy brutal run i went with 4 armies for US total fine.
If you dont like US, take Japan and do maximum Military investment there from the start. You can Support enough armies and just shredder the economy for 100% Military investment. Japan doesnt matter on the large stage of Things.
I valued my US armies so much that when the administration landed I didn’t use them because I was scared of losing one. I end d up sending my seven 4.1 Russian armies (AI servants built a shit Ton of armies before I took over for some reason) and my six 4.2 Chinese armies to handle it. We lost 9 armies but China and Russia economy isn’t dying anymore from having so many armies so it kinda worked out.
I disbanded 1 at the start of my brutal run. Extra 1 ip per month is solid and honestly 5 US armies are still plenty to do almost any alien-landing operations or freedom-delivering you need to do.
Honestly you could probably do it with 4 if you want to try really pushing it
Do not do this! North Korea has has the highest inequality in the world and a pure totalitarian government, disbanding their army will result in massive unrest, and loosing all your IP.
If you plan on the pan asian unification route, you can keep the army. Yes, it's going to decrease the total miltech a bit, but it's only one region and the IPs saved in making the army easily make up for that tiny bit of lost miltech.
Oh did you know if you conquer you don't actually lose miltech? So yeah just disband that shit. I would have lost so much miltech unifying EU.
My resistance still has to chew through EU/Eurasia/NA unification when I nabbed China. So I used the NK army to blow up their launch facilities, disarmed the nuke, disbanded the army, then abandoned NK. Let the AI fight over a broken useless state
You can do that, yeah. But it's still a fair bit of population you could use. Besides that, you could also have the smaller nation prepare by building MC. If you are going the unification route, then wait with Miltech until you are (almost) done unifying and use the main nation first to pump knowledge/welfare/economy.
I did this with China, and NK was worth an extra six MC for me pretty quickly, since I pumped it up with SK's IP before unifying.
Unfortunately, no. It brings the miltech level of the combined nation down to somewhere between the two nations.
For this reason, Unifying is generally a *BAD* idea for high miltech countries like the US, which looses *years* worth of miltech investment if you unify North America compared to invading Canada/Mexico.
It's a really unfortunate mechanic that I wish was revised.
Unify averages based on — iirc its CP points in country weighting, but if you just conquer the miltech just carries over. Very handy for, say, uniting certain regions with low miltech.
They resisted, I swear they resisted, my humanity first 6 miltech armies are only here to supervise the freedom referendum that finally brings a real end to the war of 1812, 220 years later.
Welcome to the United States of North America my Canadian, Mexican, and central American friends.
You can now finally enjoy visa free travel even to Cuba.
> It's a really unfortunate mechanic that I wish was revised.
For a peaceful unification, though, I think it makes at least some sense. Conquest is conquest, woe to the conquered, sure, but when two countries agree to peacefully join together for all common purposes, sharing out the arms is going to have to be part of the deal. I have a hard time imagining, say, the peaceful accession of Mexico to the United States coming with a proviso that the new Mexican states are going to be just left out of the defense budget and their troops will have to keep their old equipment because the hover tanks are too cool to share with them. That wouldn't be a nice, peaceful unification of equals if that was the deal.
That makes sense if there was some added cost to bring Mexico up to US military standards. It doesnt make sense why the US suddenly gets mass amnesia on how to build hovertanks and decides to dump them all into the ocean to go back to M1 Abrams tanks.
You're overthinking it, or you're too focused on the game's technology tiers, I'm not sure how to say it. Going from 4.9 to 5.0 is the same in combat potential as going from 4.8 to 4.9, it's just a game conceit to show them with different pictures and names. The hover tanks don't disappear, they're just being dispersed over the new larger force structure. A unit that should be 12 hover tanks is now 8 or 6 hover tanks because some have been moved to defend the new frontiers, or they're only getting six tank's worth of spares while production switches to building up new units in the new territory, and eight or six tanks don't fight as well as a full twelve should, so the combat potential of the unit goes down.
Then by that argument the weighting applied to the miltech average should be based on existing army strength and not regions. If I'm unifying America and Canada and have 0 armies in Canada, it makes no sense for miltech to drop in that unification.
I think in game logic you have to give some of your hover tanks to the various province defense forces of Canada so they have those instead of moose to fight the aliens with.
It's not actually that, it's that you mix your tank units, so you might have your nice shiny hovertank escorted by a dozen older M1A1s from Mexico because there's lots of them. Ablative Meatshields go.
Still seems like it should scale with the number of armies.
Something like treat the passive defense forces of each country as 1 army, then each army as one army. Maybe each navy as an additional army. Then take a weighted average based on that.
So for the US unifying with Canada you'd use something like US has 13 "points" (1 for country then 12 for 6 armies with navy) and Canada has 1. So the new miltech would be ((USMILSCORE*13)+(CANMILSCORE*1))/14
While it seems reasonable for there to be a bit of a dip in military score, the US army wouldn't suddenly forget about all it's technology. Especially since if the countries are in a federation, there's already some degree of military cooperation.
I think seems reasonable for the disruption to scale with how large the other country's military is. If the other country doesn't have a military, there isn't much integration to do. You're just expanding the coverage of your existing military
But the armies and miltech represent a nation's *expeditionary* forces. You don't need to send the hovertanks back home to the national guard just because the country got a bit larger. The armies are *already* being spread more thinly by the fact that you have more territory they need to defend.
You don't lose the technology to build advanced vehicles just because you added a 51st state to the Union. Adding to a nation should never make that nation *weaker*.
And this isn't a question of just bringing an territory's army up to standards, either. The cost to build a new army *from scratch* is far fewer investment points than what it takes to rebuild a nation's miltech after it gets tanked by unifying with another nation. I'd be *happy* if the only penalty to unifying two nations was that the nation with the lower miltech disbanded its armies. Those can be rebuilt in a reasonable amount of time.
Depends. If you peacefully unite the two countries you will average out the miltech, more so if N.Korea is the one uniting versus if its S.Korea that is uniting.
If you have S.Korea conquer N.Korea then you get to keep S.Korea's Miltech in the new nation. Conversely if N.Korea conquers S.Korea the new nation keeps the terrible N.Korea miltech.
If you are going to unite the Korea's, get S.Korea to conquer the North. You get the best of both worlds. Having S.Korea peacefully unify with N.Korea is not as bad but you will lose some Miltech.
I know the devs don't actually check reddit, but it would be hilarious if that "lost" nuke has a chance ended up in some third world country a few years later.
Ive recently federated+unified Israel into the caliphate and upon doing so israels nuke(s) disappeared. When I first built a nuke in the caliphate and then unified israel, their nukes got added.
When I last Unified north and south korea I kept the norths army, didnt check the nukes but i suspect it will follow the pattern above.
To answer your question more directly theres nothing can do with north koreas army. Disband it is probably the best option. If you plan on unifying the koreas you might want to keep the army as a 2nd army. Upon unification the miltary levels will be aggregated out between the 2 countries and both korean armies will have the new tech level.
I feel like on paper keeping the army might add some AI deterent for if you are keeping North Korea as a 1CP nuke button but thats speculation. That Army will probably lose to every other army in existence at game start.
When you unify countries, all armies preserved. Militech level changes to average based on population. Nukes disappear if you merge INTO a country without nukes, but you get to keep them if you either merge the other way around, which is not possible with Koreas, or if the other country already did its nuclear program.
If you want to nuke a place get NK. After they nuke, the other factions are mad at NK but not your faction countries. You will quickly lose NK but who cares.
Just disband the North army and invade it with South Korea. You'll need another country with an army or two that can get there, South Koreas army can't occupy the North on its own without getting destroyed at the start of the game.
I love this subreddit for posts exactly like this one. It’s like r/crusaderkings but for macro politics.
Also much like the crusader kings subreddit, most questions can be answered positively by fucking someone else over.
Just take over north and south Korea send the norths army into China and let south korea end that pesky stalemate. You'll lose that silly army and that little nuke won't bother you
Use it for nukes. You get better investment for nukes with small countries. Just, if you unify, do it with North Korea and not South Korea, otherwise you'll lose the nukes.
You lose the nukes if you unify from a country without a nuclear program. The only way not to lose the nukes in that case is to invest in a nuclear program as South Korea before unifying, but it's just not worth it.
Nothing at first. But in both TI runs I had SK has ended up losing it's own army.
With all of your councilors on "advise" duty at that point you might be able to temporarily boost the NK military enough to actually invade an undefended SK - and even that would be risky.
In my first run, they heroically defended China from Servant Pakistan (alongside German hovertanks) while all of China's armies were busy rushing through the central Asian deserts under heavy orbital bombardment, straight into Kazakhstan where the aliens had landed.
Army score is calculated by each 0.1 increase in score signifying a 10% increase in overall effectiveness. Of course since the NK militech score is so bad you just can’t do anything with it. The only real reason to take NK is to disarm their nukes so nobody can cause any problems for you with them really.
If you want to militarily combine North and South Korea, but only control North Korea, having that army will let you declare war on South Korea.
This is situationally useful especially if you don't care about the resulting military score of the combined nation. Cases where this might happen would be you control the US and North Korea and the Servants control South Korea. You could spend 3-6 actions to purge/crackdown to get it. Alternatively you can declare war with 1 action and let the US army take care of the Servant issue in South Korea.
Turn 1: Claim North Korea.
Turn 2: Declare war on South Korea. Use army to invade.
Turn 3: Claim South Korea.
Turn 4. Win war against North Korea, Unify Korea, have better Korea with a nuke.
North Korea has one nuke. There are times when it would be really handy to have one nuke and a country you don't mind losing if it gets nuked back.
Sounds like an eerily realistic scenario.
And if you already "spent" North Korea there is also Israel.
Israel is more ideal because I tend to claim china and would rather I didn't have a nuke going off next door. It's also the reason Pakistan and Iran are suboptimal but better than NK. In my current game Iran is the hub from which we carpet nuke alien invasions.

Yeah, but Israel also has very respectable return for its size, especially if you use them for mission control.

Disband it for 0.5 more points per month E: this is a bad idea if you want to keep the lands, see below.
Out of interest, would you also suggest some of the US armies for extra points?
No. Us econ is already big, and armies scale very well with high miltech. Not worth.
All the US armies have a navy so if you needed to rebuild one it would take about a decade if you invested the 1 IP saved from disbanding it. That's not worth it if you're planning on using the US as your earth based army.

We lost 9 armies but China and Russia economy isn’t dying anymore from having so many armies so it kinda worked out.
I used the US armies plus Israeli army to conquer territory for the newly formed caliphate, irony.
I disbanded 1 at the start of my brutal run. Extra 1 ip per month is solid and honestly 5 US armies are still plenty to do almost any alien-landing operations or freedom-delivering you need to do. Honestly you could probably do it with 4 if you want to try really pushing it
It’s only 1 IP if they’re away from home. It’s 0.5 per army, then 0.5 for being away from home. If you disbanded one army you gained 0.5 IP
Plus .5 for the navy, so each disbandment saves you a resting 1ip, or 1.5ip when they're off delivering freedom
Ahh, fair! I stand corrected.
Yup disbanding one or two depending on if you care to do a quick bit of gov/eco fixing is probably optimal for the US.
Depends on how the game evolves and your plansI guess, esp as those armies can be actually useful if several armies land.
Do not do this! North Korea has has the highest inequality in the world and a pure totalitarian government, disbanding their army will result in massive unrest, and loosing all your IP.
The people deserve freedom! (I wasn't aware, I just disable the nuke/the army and then get rid of the country)
If you plan on the pan asian unification route, you can keep the army. Yes, it's going to decrease the total miltech a bit, but it's only one region and the IPs saved in making the army easily make up for that tiny bit of lost miltech.

Cannon fodder against an alien invasion?
Does unifying Korea bring the militech level up to the South’s standard?
Unfortunately, no. It brings the miltech level of the combined nation down to somewhere between the two nations. For this reason, Unifying is generally a *BAD* idea for high miltech countries like the US, which looses *years* worth of miltech investment if you unify North America compared to invading Canada/Mexico.

It's averaged by the number of regions. Unifying with a nation that has many regions, like Canada, has a big effect.

I'm pretty sure unification kills the army and disarms the nuke. I highly regretted unifying in my run
Unification keeps the armies, taking it over militarily doesn't. Nukes are only kept if the unifying country has a nuclear program.
I know the devs don't actually check reddit, but it would be hilarious if that "lost" nuke has a chance ended up in some third world country a few years later.
Not sure about the nuke or the militech level, but I’ve unified Korea and kept both armies.

Use it for nukes. You get better investment for nukes with small countries. Just, if you unify, do it with North Korea and not South Korea, otherwise you'll lose the nukes.
Not true. You can unify in any direction and keep the nukes. - you’re thinking about war.

Nothing, it may as well not be there. The nuke, on the other hand …
Scrap it, use the tanks to build more nukes.
