HOI4 Dev Diary - Chain of Command

Hi everyone and welcome back to regular dev diaries. This and upcoming diaries will be covering stuff happening in the 1.5 "Cornflakes" update as well as the unannounced expansion that will come out together with it. One of the main focuses of those can be summarized as "making players care more about armies, leaders and troops" (our DLCs tend to have 1-3 main focuses or missions). The first feature that touches on this, and the topic of today's dev diary is adding a military chain of command to the game.

After Hearts of Iron III, where something like organizing the soviet chain of command could take about an hour of the players time we decided that we wanted something that was a lot less effort to work with for HOI4. We basically settled on a flat level with field marshals with no restriction on commanded divisions, and generals with a limit on division count but with a different set of traits. Over time we felt that we lost a bit too much of the WW2 military flavor with this abstraction, so we started thinking about how to do it in a more interesting way.

What we have done now for 1.5 is that field marshals are now leading an Army Group, which is a certain number of Armies (what we had before) led by Generals. There are then places in theaters as before. Theaters are like before just a geographical organizational tool for the player and don't have a commander or the like to keep them as flexible as possible. This means that we have a Theaters->Army Groups->Armies->Divisions structure now.
While the Generals still come with a soft cap for how many divisions they can efficiently command, the field marshals will now have a number of armies they can efficiently command.

I also want to make sure to point out that this is still very early on in development, so stuff is very likely to change, and some stuff aren't completely working as it should yet. So we are showing you this in progress rather than showing a completely finished feature, and as always any numbers you see are extremely subject to change ;) Also I very sneekily hid the topbar for now ;)

When it comes to controlling your troops the new system introduces some changes to the battle planner. You can either do a plan for each army in the army group, or have a central plan for the whole Army Group where each army has a part of the frontline assigned as its responsibility. You can also do a mix, in which case an Army will finish its plan and then fall back to executing the Army Group's plan. We are still iteration on this stuff though but I figured you all wanted to know how it would work in practice.

Something that does not really come across in the images is that we are working on ways to streamline the process for setting up fronts using the new army groups. This should make at least the basic cases feel smooth to set up, even with one more command level and more armies without a ton of extra clicking.

The sharp eyed reader will also notice that we have removed the skill level for generals. This is now replaced with separate skills of different kinds. Attack, Defense, Planning and Logistics. Attack and Defense do what you expect while Planning improves planning speed and Logistics lowers supply consumption. Field marshal stats apply together with army general stats at a reduced capacity, so you will always want to have a chain of command for best efficiency.

The chain of command feature is going to be part of the free update, although there is some cool DLC features that tie into it we will be revealing in later diaries. Also expect to read more details about the system itself like how things in combat are affected etc.

See you next week when we will be taking a look at national unity...
 
@podcat

Are there any plans to change/tweak frontline mechanics? My problem with the current frontline mechanics is as follows:

It's not possible to have a single frontline along the borders of two different countries you're not at war with. An example of when it's annoying: when playing the USSR and waiting for the German attack it would be far more convenient for me to have a single front along the German and Romanian border, for the troops to be automatically evenly distributed along this front, as I know that Germany will call Romania into war immediately. After the attack happens I will be able to have single unified frontline, but I'd much prefer to be able to create it while still preparing for the German attack.
 
Setting up a proper OOB was one of the most enjoyable things from HOI3 - I wish you would expand on it, rather than simplify it this much. Still early so better wait perhaps, but these images look still extremely simplified. Are there Army assets? Corps assets?

This. This is very important.

I'm tired of having to go fight the USSR as part of the Allies-Comintern war as China, and then have to create three borders for Sinkiang, Mongolia and the USSR, before splitting my 215 divisions up.
 
I'm kind of hoping this can be disable-able when starting new games, so that you can keep the old way of command if you want.
 
So, let's say that we're playing as one of the minors that doesn't start with any commanders, does this mean we'll need at least two commanders, or can armies operate independently without a field marshall?
You can generate some shitty lvl 1 marshals to lead your glorious Luxemburgian armies though.
 
i have a question,in the next updates or dlc maybe,will you focus on the minor powers like Croatia and bulgaria for axis, south africa and egypt for allies, because these countries need their focus trees updated,but anyways good dev diary,somewhat complex for a newbie in hoi4 but i like it

South Africa was cover in TfV.

As to Bulgaria, You come up with a few Focuses. The Devs tried but they could find any. Croatia was never really independent, just a puppet as Egypt was so not powers at all.
 
Maybe,but still these little countries like Croatia,Bulgaria and Egypt should have their own focus trees,they were important,maybe puppets but they had their role in the war,for example Djalova Pukovnija (Djals Battalion)was a croatian batalion fighting in Stalingrad,the thing is that if these minors had something in them they would be more attractive to be played
 
Plus i am a Croat and some of my friends will also get the game,so being able to have an interesting Croatia would be fun
Croatia should be so far down the list of countries that get a unique nf tree that I wouldn't expect it for several years if ever.

Maybe the odd event etc yes but otherwise that's dev time that should be spent else where.

A full overhaul of the majors and the addition of China needs to happen before any more minors are added imo.
 
Thats true and the minors should be focused last,but I hope that one day Croatia will also see its place in sun
I'm sure there's a mod for Croatia.
 
Podcat himself admitted that they swung the pendulum too far. And now they are trying to correct that mistake. Swing it back to dead center atleast. And who knows, if they design this CoC properly and the AI handles it extremely well, it could one day be moddable to increase the levels, which I think would satisfy EVERYONE (would need severe GUI modding though, more levels than they current propose would be god awful ugly IMO). I personally don't want this game to be designed for first time strategy game players.

i get it and im trying to look on the bright side its just, i hated OOB/HoI3 so much i almost swore off Paradox games. It was by pure chance my mom brought Vicky 2 for Christmas and got me to stick around.

im just worried there going to slowly go to far again.
 
Great stuff devs!

I'd like to add my hat into the camp that adding a dedicated Corps level for the CoC would be excellent. I've found plenty of instances in the game where I want to control about five or less divisions and give them specific commands. Now obviously you can still do that, but giving them their own orders would be great for immersion purposes and good for gameplay. I've had my fair share of screw ups where I deleted or messed with the orders for the rest of the army while telling my pseudo-corps to do a Spearhead, or reinforce part of a front, etc etc.

If you can't justify it due to the resources that would have to be spent researching and creating portraits for a lot of corps commands, perhaps let it be moddable for us who don't mind dozens of random dues running around? :)

Also, very very interested to see what you're going to do with National Unity. I'm hoping it'll will make capitulating a country a bit more complicated to what is effectively king of the hill.

Cheers
