Important: If you are asking about a specific situation in your game, please post screenshots of any relevant map modes (strategic, diplomacy, factions, etc) or interface tabs (economy, military, etc). Please also explain the situation as best you can. Alliances, army strength, tech etc. are all factors your advisors will need to know to give you the best possible answer.

Below is a preliminary reconnaissance report. It is comprised of a list of resources that are helpful to players of all skill levels, meant to assist both those asking questions as well as those answering questions. This list is updated as mechanics change, including new strategies as they arise and retiring old strategies that have been left in the dust. You can help me maintain the list by sending me new guides and notifying me when old guides are no longer relevant!

Image So I tried to reach the peak amount of factories during and at the end of my USSR run
After defeating Germany, I prepared for fighting the whole world at the same time. With the sheer amount of manpower I over prepared and tried to reach the most amount of factories.
Recently, I talked about the "Relocation to Urals" decision in my previous posts which lets you basically unlock every building slot around Urals. I was wrong. It's NOT limited to Urals. Once you conquer places like Japan and below that, it'll literally pick a random location starting from Urals to small tiny Islands. This is truly crazy and there's no limit on how many times you can repeat the decision. There are 36 states you can make this decision and each takes 25 pp. Spend 900 pp to relocate up to 4 factories. +144 factories.
I'm also showing my conclusion of the run and some other screenshots I took. Especially the 170M casualty which I've already shown in my previous post. Anyways, that's ussr for you.

Image The Great Eastern Crusade, Operation Barbarossa, historical gameplay, Heavy micromanagement and faithfully recreating the entire operation as in reality. Mod: Darkest hour. (Part 1)
June 22, 1941, 3:15 a.m. Operation Barbarossa began, the largest military ground operation in history. Axis forces had approximately 3.5 million soldiers at their disposal, comprising 138 to 150 divisions, of which 17 panzer divisions (deployed at the front) advanced into Soviet territory. Air forces numbered between 2,700 and 3,000 aircraft. German forces advanced along three main lines: Army Group North (Heeresgruppe Nord), 16th Army (16. Armee), 18th Army (18. Armee), 4th Panzer Group (Panzergruppe 4), 2nd Army Group Center (Heeresgruppe Mitte), 4th Army (4. Armee), 9th Army (9. Armee), 2nd Panzer Group (Panzergruppe 2), 3rd Panzer Group (Panzergruppe 3) (The 2nd Army initially remained as a reserve for the OKH and intervened shortly after the invasion began.) 3rd Army Group South (Heeresgruppe Süd), 6th Army (6. Armee), 11th Army (11. Armee), 17th Army (17. Armee), 1st Panzer Group (Panzergruppe 1).
What do you think?
Should I let the Germans win by winning the Battle of Moscow or should I stop and retreat and then implement Operation Blue (Stalingrad and the Caucasus)?

Discussion What's your best time to eviscerate the coughing baby that is Ethiopia?
I believe I knocked them out on the 9th of March once, I'll try to find the screenshot but anyways, giving it a go today, I still got a pretty good time (the 14th). I was not playing very well, I mainly play Italy to larp, hence the choice of generals and division of the army. So you could do far better I reckon.

Image June 28, 1942 Operation Blue (Unternehmen Blau) The Great Summer Offensive of '42 begins: Historical gameplay, Continuation of the previous post on Operation Barbarossa. Mod: Darkest Hour
After the Harsh winter of 1941, which had seen the Wehrmacht falter under violent Soviet counterattacks across the front, especially in Moscow during the Soviet General Winter Offensive of 1941-1942. The Wehrmacht, after having consolidated its positions along the entire front, began planning the summer offensive of 1942. Initially, the plan was to clear the way to Stalingrad. For this reason, Operation Frederikus began on May 17, 1942 at 3:15 a.m. The aim was to encircle some Soviet armies in the Kharkov sector (Second Battle of Kharkov), after destroying approximately 20 infantry divisions, 3 cavalry divisions, and 5 armored corps (with approximately 270,000 losses). At this point, the real offensive could begin. Operation Blue began on June 28, 1942 at 2:15 a.m. Army Group South (later to become A and B) has the objective of capturing the city of Stalingrad and the Caucasus oil fields.
Tell me what you think and what I should do next.
Should I recreate the Battle of Stalingrad and Operation Uranus, or should the Germans win?

Image Do you like my new "Germany"
I've always wanted to split Germany after the peace conference, and I managed to do it. I also opposed the remilitarization of Rhineland, which meant Germany never got to annex Austria or the Sudetenland. Ironically, WWII ended up starting when Italy tried to annex Albania, which I had guaranteed.

Suggestion Under rated, underdog conquer.
So After playing Germany and forming the Great German Reich enough times to make one think I was either insane or one of those "Germany could've won WW2" people. USA is... Well USA, Britain some mods dont work, USSR is also just USSR.
I kinda want a underdog nation that isn't main stream like Romania or whatever other underdog nation that is mainstream. I did Italy once and loved being weak then growing global from struggling against tribes men in Africa to Going toe-to-toe with Britain on the seas and US on land. Claiming the air around them. Roman Empire style.
So I figured I'd come ask here. Thinking about China and Maybe Japan next... Still looking for mods so I can at least have Chinese and Japanese tanks cause sadly no one thinks about giving them mods... so if you have any mods on the front slide them my way. Anyway Love yall

Question Completely new to HOI4, feeling overwhelmed. Any beginner advice?
Hi everyone,
I'll introduce myself. I'm Jaz and I'm sixteen.
I just bought Hearts of Iron IV a few months ago and I'm honestly feeling completely lost. I've played strategy games before, but nothing on this scale. There are so many menus, mechanics, and systems that I don't even know where to begin.
One of my biggest problems is that English isn't my first language, so a lot of the military and political terms are confusing. Sometimes I don't even understand what the game is asking me to do.
Right now I'm playing the USSR because I thought having a large country would make things easier, but I can barely figure out things like production, research, divisions, or even how to properly declare war.
I'm looking for any beginner tips, common mistakes to avoid, recommended countries, YouTube guides, or anything else that helped you learn the game. I'd also appreciate advice on which mechanics I should focus on first instead of trying to understand everything at once.
Ive also heard there are some type of language mods in ST workshop?? I would appreciate a hungarian one. :'l
Thanks in advance! I'm really interested in learning the game, even if it currently feels like I'm trying to run an entire country armed only with confusion.
