# HOI4 Beginner Combat Guide | Win MORE Battles

> Source: [HOI4 Beginner Combat Guide | Win MORE Battles](https://youtube.com/watch?v=x1OYc4gaxg0)

## Summary

This video is a beginner's guide to combat in Hearts of Iron IV (HOI4), covering the fundamentals of division design, terrain, and both offensive and defensive tactics. The creator explains key mechanics like organization and strength, then provides practical tips for winning more battles, from planning attacks to using entrenchment and air support.

### Key Points

- **Division Strength and Organization** [00:15] — Divisions have orange strength and green organization bars. Strength reflects manpower, supplies, and equipment (100% when full). Organization indicates readiness to follow orders; when it runs out, attacks stop and divisions retreat.
- **Division Designer Basics** [01:10] — Using the German starting infantry division as an example, the video explains stats like HP, defense, organization, breakthrough, and soft/hard attack. Infantry provides high HP and defense but low breakthrough, making it good for defense but poor for attacking.
- **Adding Offensive Power** [02:46] — Adding artillery battalions increases soft attack and breakthrough but reduces organization and increases width and equipment needs. Tanks and mobile artillery add firepower and breakthrough but lower organization. Balance is key; keep organization around 40.
- **Common Mistake: Equipment Shortages** [03:40] — A major error is designing divisions with equipment you cannot produce, like adding three artillery battalions to all infantry divisions. This reduces strength and experience, making divisions perform worse in combat. Focus firepower in fewer divisions and ensure sufficient equipment.
- **Terrain and Combat Width** [05:31] — Terrain affects combat width and provides penalties/bonuses. Plains are good for attacking, forests give defensive bonuses but penalize movement and attack. For Germany, use 20-width infantry for forests (three fit in 60 width) and 23-35 width tanks for plains.
- **Experience and Training** [06:55] — Divisions have experience levels; level 1 gives -25% combat modifier, level 3 gives +25%. Train divisions to level 3 before war to gain a positive modifier, though it consumes equipment.
- **Supply and Logistics** [07:23] — Ensure sufficient supply by having high infrastructure, upgrading railways (with No Step Back DLC), setting motorization priority, and capturing/defending supply nodes. Trucks and trains are needed for efficient supply lines.
- **Air Superiority and Weather** [08:05] — Air superiority with fighters can reduce enemy division speed and defense by up to 30%. Bombers directly damage organization and strength. Weather causes attrition, reduces speed, and disrupts air operations; defenders suffer fewer penalties.
- **Reserves and Reinforcements** [08:51] — You can place more divisions on a tile than combat width allows; they reinforce as frontline divisions retreat. Be careful not to overcrowd, as it causes logistics penalties. Keep reserves behind the line for defense or attack.
- **Generals and Planning** [09:21] — Assign attacking armies to generals with high attack skills; supply and planning are secondary. Create a front line and attack line to gain a planning bonus, which boosts attack stats. This is especially useful against entrenched enemies.
- **Multi-Directional Attacks** [10:28] — Attacking a tile from multiple directions increases the front line and combat width, putting the defender at a disadvantage. Always look for regions that can be attacked from several of your tiles, even if they are forest or hills.
- **Railway Guns and Anti-Tank** [11:09] — Railway guns reduce enemy entrenchment and are effective against forts. To counter enemy tanks, increase your armor piercing above their armor value by researching anti-tank modules and using specialized divisions.
- **Attack vs Defense Mechanics** [11:49] — Each attack point above the defender's defense counts as four. For example, 150 attack vs 100 defense results in 300 effective attack (50*4). This is crucial for overwhelming defenders.
- **Defensive Tips: Entrenchment and Terrain** [12:18] — Divisions automatically entrench when idle; max entrenchment can be increased with Old Guard field marshal, Grand Battle Plan doctrine, and engineer companies. Defend behind rivers for a 25% defense bonus, and use mountains, swamps, forests, and urban terrain.
- **Fortifications** [13:13] — Build multiple levels of fortifications in regions that can be attacked from multiple directions. Each level adds -15% to the attacker, but costs increase as you approach level 10.

### Conclusion

The video provides a solid foundation for HOI4 combat, emphasizing the importance of division design, terrain awareness, and proper preparation. By balancing offensive power with organization, ensuring supply and air support, and using tactics like multi-directional attacks and entrenchment, players can significantly improve their chances of winning battles.

## Transcript

This tutorial will teach you how to win more battles as a beginner at Hoi4. The basics are covered extensively and every topic is timestamped. I will also make a more advanced tutorial, so be on the lookout for that too.
Now let's begin. The first thing we're going to look at are divisions. These are the building blocks of your armies, so it's vital to know how they work. Each division has an orange strength bar and a green organization bar.
If you hover your mouse over strength, you're going to see what that means. When a division has all the manpower, supplies, and equipment it needs, it's going to be at 100% strength. As for the green organization bar, this gives you an idea of how willing your divisions are to do what you tell them to do.
So if you're attacking and you run out of organization, you stop attacking, and if you're defending and the same thing happens, your divisions will back away from a battle. As your divisions and armies fight, you notice that most of the time, organization is the first thing to go down,
which causes you to lose battles. Strength will also go down but usually at a much lower pace. Okay, now we know about strength and organization. So let's see how you can alter them with your
division designer. What we're looking at here is the starting German infantry division. You have nine infantry battalions and two support companies that we can ignore for now. If we take a look at the stats, we're going to see that this division has high HP and defense in addition to decent
organization. These are the high stats, so which are the low ones here? Well, the breakthrough is not great, and this stat translates to how many attacks you can avoid while you yourself are
attacking. The soft attack is kind of mediocre, and the hard attack is super low. For these two attack types, you need to look at the hardness of your divisions. Tanks and mechanized battalions add hardness, as they have armor that small bullets can't pierce. So, a division with high
Hardness won't be affected much by Soft Attack, however it will take damage from Hard Attack, and the reverse is also true. If your Soft Infantry is facing a division with lots of Hard Attack but not that much Soft Attack, then it won't suffer much damage. Anyways,
if we continue to add Infantry Battalions, you will see that HP and Defense get the highest boost from that. Long story short, this is how the game tells us that this is a great defensive divisions which sucks at attacking. Do you need to build these divisions? Absolutely,
they are going to be the backbone of your army as they will make up the most of your front line, but don't be surprised if such a division is not great when attacking. Now how can you make one of these divisions more attacking? Well, you include battalions that add more attacking stats and
something that usually gets paired with infantry is artillery. See, adding a single arty battalion gives you 25 soft attack and even some defense and breakthrough, but it comes at the cost of lowering your organization. Plus it makes the division bigger, so it takes up more space on
the front line and it needs more equipment as well. The same principle applies to tank and motorized divisions as well. There you will have motorized infantry increasing organization, while
tanks and mobile artillery add firepower and breakthrough, but they decrease organization. And how much of these stats you receive also depends on things like which doctrines you go for or how advanced your weapons and technology are So to summarize making a good division is a balancing act where you ask for your power but try to keep your organization at a decent level and a decent level
is around 40-ish, so don't go much below that. Before we move on to other topics, I need to mention one huge mistake that even advanced players can make. You will see a lot of division template
videos around YouTube and even if you make a template of your own, you might just add equipment that is simply not in your stockpiles and you can't produce enough of with the factories that
you have. For example, if you add three artillery battalions to all of your infantry divisions, there's a high chance you won't have enough artillery for all of them, which in turn will lower the strength of all of your divisions and reduce their experience, making them perform worse
in battle. In a way, you're trying to cook a dish without having the right ingredients, so you can't really expect great results from that. Big guns like arty and tanks are expensive, so concentrate that firepower in fewer divisions, and make sure you have enough equipment and
reserves to keep these divisions supplied in the long run, and this is what will make them effective. To add firepower without altering your defensive division design, simply press duplicate and then continue to add attacking battalions. Now let's move over to the other
super crucial topic for land battles, terrain and combat width. If you press F5 and zoom out on the map, you will see the terrain in which you are likely to fight. And each type of terrain tile
has different specifics. For example, a plane's tile has a combat width of 70. And if we check the terrain modifiers on our infantry and tank divisions, we will see that they get no bonuses
or penalties to attack or defense while fighting in a plain province. Let's compare that to a forest. Forests have a combat width of 60 instead of 70, and when you're defending in a forest, you suffer 10% less damage from enemy air support.
Also, infantry gets a 25 defensive boost there plus a small movement bonus, while tanks get a sizable movement and attacking penalty in forests, but they also get a defensive bonus. What does this all mean?
Well, if you can help it, try to attack plains regions and defend in forests. I'm taking these two as examples as they are the most common throughout Europe, so it makes sense to take note of the combat width they have and make your divisions fit
perfectly in that type of terrain. That's not to say that there are no other terrain tiles, however. For example, Italy and the Balkans have lots of mountainous regions, so if you're primarily going to wage war there, you might want to make mountaineer divisions with 25 width so
so they fight effectively in that type of terrain. To make this info useful, let's take Germany as an example. Since the forest style has 60 widths and there's a lot of forests around, you want to make your defensive infantry divisions 20 widths, so three of them can fit
perfectly in a forest region. As for attacking infantry, you can make them 29 or 30 widths, so they also stack well in forests. Meanwhile, your tank divisions can be around 23 combat width
and can also involve the 35 width, so they fit perfectly in the planes regions that they are likely to attack. Now, I'm going to split the video into tips for attacking and defending, but before I do let cover some topics that are good for both of these situations Also if you do appreciate the video I would appreciate your likes and subscriptions Wink wink Step number one experience Each
division has a certain experience level that you can see here. The lowest is level one, which gives you a 25% negative modifier when you are in combat. Without going to war, you can train all of your
divisions level three, so you get a positive 25% combat modifier. This will also give you army experience, but it does consume equipment. Still, you should always train your divisions if you can
afford it. Number two, supply. If you don't get enough supply, you won't have a good time, regardless if you're attacking or defending. To make sure you get enough of it, assure that you have high infrastructure levels, and if you have the no-step back expansion, you can upgrade the railway systems,
make sure that your armies have high motorization priority, and you also need to be mindful about attacking and defending supply hubs. Taking an enemy supply hub can make all defenders in the region suffer greatly, while keeping it can force the attackers into a stalemate or even a withdrawal.
On top of that, you need to have enough trucks and trains so your supply lines run efficiently. Number three, air force. Ground battles are not only about divisions. Your air force can have a
huge effect on the stats of your armies. If you achieve air superiority only with fighters, enemy divisions can get up to minus 30% on their speed, defense when defending, or breakthrough if they're attacking.
And if you add bombers to the mix, then enemy divisions will suffer direct hits to their organization and strength. Number four, weather. Now this can play also a big part in the game. You can get extra attrition, reduce speed, attrition for your supply trucks, it can disrupt your airplanes, and so on.
In many cases, you need to be more mindful of weather when you're attacking, as defenders tend to suffer fewer penalties. And lastly, reserve and reinforcements. You can still put more divisions in a tile than combat width allows, and these can reinforce the battle as the divisions that are in combat back out.
Just be careful, as swarming a region with many divisions can result in a logistical nightmare. You can always keep some divisions in reserve behind the front lines, it can be later sent in to defend or attack.
Now let's move over to some attacking tips. As I said, I will make an advanced tutorial for how to do Blitzkrieg, but learning the basics here is a must. Number 1. Generals. You need to organize your attacking troops into armies led by the proper generals and field marshals.
In this case, their attacking skills are the most important, while supply and planning are secondary, but also quite important. Generals also have certain traits that make them better for different divisions and terrains, so always be on the lookout for those.
Number 2. Planning. When you're done assigning generals, create a front line and add an offensive line to it to make your armies go into position and start preparing. This will eventually give them a planning bonus, which will further boost your attacking
stats. This is especially useful if your enemy is organized and dug in behind a river. But if you're not facing that much resistance, you can skip planning and just continue to press the advantage that you have and attack.
Pressing the staff office plan mission will make you plan a lot faster and your doctrines national focuses the skill of your generals can also improve the speed and the total planning percentage bonus you get Tip number three
is attacking from multiple directions. We already said that it's good to attack strange regions, but not all of them are equal. For example, this strange tile on the Polish front can only be attacked from one place, but the one below it can be attacked from four of your tiles. If you attack
a single tile from multiple directions, this will increase the front line and the combat width of the battle which puts the defender at a big disadvantage. So always look for regions like this one when attacking, even if it's a forest or a hill
region, attacking from multiple directions will often help you overwhelm it. Number 4, Railway Guns. If you're in mainland Europe and can afford it, railway guns are fantastic.
They reduce the entrenchment of enemy divisions and their combat effectiveness and are also really great against forts so look to build them if you can. Number five, attacking tank divisions. Now this can be really difficult as they have armor which greatly reduces the damage they take.
To negate their defensive bonus you need to increase your piercing stat so it's over their armor stat. You can do this by researching anti-tank modules that you can put in specialized divisions to counter tanks. As an attacker your general aim is to have higher attacking stats
than the defense of your opponent. And this should be the case if you have the proper divisions, supply them well, and have air superiority. Every single point of attack you have over the defensive
points of the enemy counts not as one but as four. For example, if you have 150 attack and the defender has 100 defense, you will be attacking with 300 attack because your first 100 points of
attack will be negated by the defense of the opponent, however your 50 points get multiplied by 4. This makes defenders evaporate before you and is super important on the attack, so look to
achieve it. Now let's finish with some defensive tips. Number one is entrenchment. Much like attackers get planning, defenders get entrenchment. Just leave a division anywhere and it will automatically force it to entrench. And it will get fully entrenched once this shield icon here
gets filled up. The maximum entrenchment level can be increased in several ways, the easiest of which are choosing a field marshal with all guard and defensive doctrine, the grand battle plan doctrine path and getting better engineer companies. Number two is using terrain to your advantage.
Putting up a defensive line behind rivers is great as you can get a 25% modifier to your defensive stats. Mountains, marshes, forests and urban terrain tiles are also hard to attack
unless the enemy uses specialized divisions, so you can plan your defense in advance and then put up a stand where all the advantages favor you. Number three, if your defensive line has regions that can be attacked from multiple directions, you can build several fort levels there.
Each fortification level adds a minus 15% penalty to the attacker, but they get more expensive as you get closer to a level 10 fort, so keep an eye on that. And this covers the basics of winning more battles as a beginner.
As I said, I will be making a more advanced tutorial titled how to blitz and when it's ready I will leave it at the end of this video. And if you enjoyed my tips, please like this one, it will be highly appreciated. In the meantime, if you want to learn how to do naval invasions,
