Sudetenland always denied?
Is there a point in demanding Sudetenland if I just get denied everytime? They have massive fortifications on the border and alliance with France. Is there a way to get them to cede Sudetenland to Germany or what I am doing wrong?

If as Germany you've already started a war then it sets the AI to defend Czechoslovakia. The IRL reasons for accepting the Sudentenland and Munich Conference (and subsequent total annexation of Czechoslovakia prior to the war) was appeasement. Which doesn't work if you've already started a war.

If you haven't then the UK has something like a 95% chance to accept the taking. France follows the UK & accepts at an even higher level unless some shenangians have taken place and Czechoslovakia and France are in a faction.

Czechoslovakia on it's own has a sub 5% chance to reject it. If Austria is still around that chance doubles.

If the Germany army is roughly comparable to the Czechoslovakia army and Germany doesn't have Hungary or Poland in their faction they will fight. They will also fight if they run a faction.

If Czechoslovakia are just "in" a faction, not in charge they have a 80% chance to fight.

Thanks for the info! So basically ally Hungary and have a bigger army. And don't start wars.

Shove most of the troops on the border of France, it more often makes the UK submit

Usually I have around 70-100 divisions while I do the Sudetenland and no one in my faction, most of the time I pop them ALL on the Maginot line and none at Czechoslovakia, they submit. sometimes I put 90% of all my divisions at France and the remaining 10% at Czechoslovakia as they do have that very small percentage to say refuse.

Anyway your main concern is UK and France, thats why I always border the Maginot line. If they accept, then its on problem, is bad luck of Czechoslovakia declines but UK and France are basically the main things that determine whether you get it or not. So I recommend putting the majority of your troops on the border with France.

You don't really need anyone in your faction, hell Hungary often likes to refuse the offer of joining your faction, but you do not a rather large army


Oh I like ot cheese the game a lot so i take poland before austria and Czechoslovakia, when i do sudetenland, they almost always accept if my army is large enough, I just need to border them otherwise they usually never accept. So i can basically take poland, then austria, then czecoslovakia free of charge even though I went to war, but yugoslavia is very challenging

Basically border a lot of troops on France and UK and have big army, if you started and "finished" (the war has to be finished) a war and the allies are not at war with you, you can still take czech as long as you have a big army

Troops on the border really help determine whether you may get it or not, even with a huge army, sometimes i get refuse because I have like no troops on my border with them,

Is it worth building Pz3's? I don't know how people have medium tank divisions ready for 1939-1940? Also do you overrun Poland with the 3 Pz2 divisions and starting infantry or wait until you have more infantry divisions?

Many things in game like AI decision is driven by world tension - so especially earl;y wars caused by player tend change behaviour to more fighting spirit in general. Also things like military power on borders comparison or diplomatic relation relation same as if neighboring country is part faction play role.

As for tanks - do not make new divvisions but have some rpoduction for replace loses. Role of tank divisions is make fast breakthrough and encircle the pocket. Hence not frontline army of divisions but jsut few dedicated and for that even 3 is fine at beginning. Light tanks are perfectly ok even for France (actually still usable later game too but mediums are much better). You can get some focus for early research but have mediums ready for Poland is quite challenge production wise. Good strategy is start replace batallion per batallion in your light tank divisions as your production goes up and convert all remaining light tanks to light SPART - this allow you very good divisions likely way before your opponents without wasting too much production.

Having some medium tanks, outdated or not is better than having no medium tanks.
The only one I can recommend not wasting too much on are Heavy Tanks I, try to go for Heavy tanks II, but if you have a huge industry, might as well just produce some heavy tank I to make up for time. Note: keep production a but slow and slowly increase it, you'll need them by the invasion of soviets but you dont need them really at poland or france

So its basically worth it building Panzer IIIs because it allows you to have medium tanks

Often I spam infantry and building a few tank divisions, I dont change my tank division to use Panzer IIIs until Poland falls whether I cheese the game or play it properly. I let my light tanks do the work in Poland and sometimes in France. Though you want to build medium tanks early so that was you invade soviets, you have a decent amount of Medium tanks in reserve or on the field, even if they become outdated.

I personally like to take a slow but strong approach for tank divisions, after Poland fall, I change them to 40 widths right of the bat so i'd only have like 3-5 Tank divisions but beefy ones.
There are other methods like spamming 20 widths or making space marines, but I'm not too familiar with that

The tank division you start with is enough fro Poland, but try to get XP in spain to make it a 20 width so that once you invade france, it can do very well. Light tanks are good but against the soviets, not so much.
developing medium tanks before 1940 is masive "reserch investment" or you weaste a focus tree , add to that you need to divert production

in SP it can be mixed bag as tanks are expensive to produce and generaly vs AI i found more relialable to mass produce infantry , with good support companies or just go mechanized

you dont really need encirclements with armor if all frontline is 70+ green

this was made even easier with spies , as you can nulyfy planing bonus of your strongest foe making their attacks even weaker and give you buffs

problem with armor i have is if it works it works but it can be unrelialable , especialy in MP , and saved reserch and focus tree's can make you stronger in other way

you can sort of go tanks lite , going light only (as they dont get penalties , and you start with them) , bank on them early on and later you can discard them

dont get me wrong as tanks can be amazing , but they dont guarantee your sucess , when i go "super infantry" i never lose (SP)

mostly i adopted that strategy as i was playing minor nations(who dont got tanks anyway) but it can be really good with bigger countries too


Generaly tanks are better if you know game really really really well as it lets you do a lot cheese , just like paratropers , but if your semi noob or want something who works "every time" infantry is way to go
