[HOI4] An In-Depth Guide to Land Combat

In this video I break down land combat in Hearts of Iron 4 into its most basic components to show how it functions. I cover everything that goes into the damage equations so you can see how soldiers actually die. Then, I take these results and extend them out to more practical uses by discussing some rules of thumb for division design and strategic planning.
Correction: /u/TheBlobber has brought it to my attention that my results for reinforcement are off. I erroneously calculated the median when I intended to calculate the mean. The true "average" reinforce rates for the base value, the radios tech, and top-tech signal companies would be 50 hrs, 14.28 hrs, and 4.76 hrs respectively.

When watching this I gained a 100% bonus to hardness.

So, in summary:

[@RorysonTV]

Finally someone who ACTUALLY knows how these things works, only took me 500 useless videos, 90% of players think breakthrough is what it sounds like, breaking through the enemy lines. lol.

[@sheharyarhusham5908]

I am left amazed and speechless at this surge of videos

[@stonedude1234]

I've played 52 hours in this game and only after a second game of America and after researching a whole bunch of land doctrine did I begin to think, "I wonder if I'm doing combat wrong..."

[@pepela8214]

Me: struggles with taking France as Germany

[@marcelodcs1]

Maybe the next video could be on how to properly draw the frontlines?

Fantastically in depth Reman. I have almost 500 hours and several YT series on HOI4, yet I still learned a whole bunch about how to optimize my armies.

So a 400 soft attack division defending against a 10 breakthrough division makes 400 dicerolls to determine misses and 33 to determine damage.

Nice to see you branching out to HOI4, which is kicking into gear with waking the tiger, with tons to analyse.

I do the same thing against the soviet union, constantly checking the capitulation bar yelling in my head "why the F haven't they surrendered yet!"

[@OliverCovfefe]

Reman if you get 50k subs will you read the Art of War by Sun Tzu?

[@dichebach]

They did a good job modeling theater-scale strategic WWII combat. Shocking how much better this combat model is than what I'm familiar with in EU and Vicky games.

[@Metrack2]

We need more awesome people like you in gaming Reman, period.

[@MrAlanis59]

It's incredible how you transition from eu4 to hoi4 with still in depth content! Congrat and thanks for your work!

Warning: When more than one division participates from one side, they can combine their attack value to overcome the defense of the opposition. For example, two divisions with 100 attacks each pull their attacks versus single division with 150 defenses. In this situation 150 attacks will be considered "blocked" and have a 0.1 chance of hitting, while 50 attacks will be "unblocked" and have 0.4 chance of hitting.

This is a fantastic video. I've been looking for someone to explain the maths behind the combat system and now I feel like I stand a chance of digging in and truly appreciating this game. Thanks ever so much for your hard work.

This video was a huge help. The micro intimidated me, but with each game im getting better, and its drawing me in more and more.
