Hearts Of Iron 4: Best Combat Widths (2024)

With Hearts of Iron 4 considered one of the most comprehensive grand strategy games set in World War 2, fans of wargames may appreciate the level of depth the game offers, especially from the perspective of wartime production and overall warfare. After players research improvements and other advancements for their ground troops, they can engage in intense land battles against enemy forces - with much of their units' strength reliant on Combat Width.

Combat Width in the game is defined as the overall concentration of a faction's ground forces. Terrain determines the base width and flanking width available to players, with elements such as flanking, naval attacks, and paradrops adding to a side's Combat Width before engagements begin. Considering how Combat Width is determined by its encompassing battalions, fans may wonder just how much is "enough" when trying to engage enemies as practically as possible. With the game offering different engagement setups, just which Combat Widths are the most practical in the game?

Updated on August 7, 2024 by Rhenn Taguiam: With the Trial of Allegiance DLC allowing Hearts of Iron 4 players to build South American nations into superpowers in the historical grand strategy title, gamers might be interested in how these countries can engage in interesting alternate historical paths. For players who are more inclined to wage war instead of diplomacy, knowing how to use the game’s combat system may allow players to dominate their rivals. This is especially the case when they learn the game’s best Combat Widths, as arranging their Divisions to cater to specific environments or setups may give them the advantage they need for more consistent victories. Suggestions include a setup that works for almost all environments except Plains and Urban settings, a filler-oriented Combat Width, and manageable variants if players can’t optimize for specific setups.

1 Combat Width 11

Avoid Plains And Urban Environments

Among lower-numbered Widths, it’s perhaps Combat Width 11 that is among the most practical to consider without dwelling too low on impractical penalties. As expected, their small numbers allow them to perform decently in Marshes and Mountains, as well as Forests and Jungles. However, Combat Width 11 does perform rather averagely in Plains, Deserts, and Hills, and may suffer from multi-directional attacks when engaging enemies in Urban environments.

Another potential setback of a smaller Division as a whole in the grand strategy title would be having fewer Breakthrough and Defense, theoretically making them much easier to take out. In order to counteract this, gamers may play into the nature of smaller Divisions having better Organization and boosting overall damage with the help of Support Companies, albeit at the cost of more Manpower and Equipment.

2 Combat Width 24

Decent-Sized Division For Fillers

The potential strength of Combat Width 25 in Marsh and Mountains can make for a surprising revelation in the nature of its predecessor in Hearts of Iron 4 gameplay, as Combat Width 24 shares similarities with other Widths of having harsh penalties in the aforementioned region.

However, Combat Width 24 can potentially fill the gaps of Width 25 when it comes to one-directional conflicts in most other terrain. Moreover, this Width’s potential for being line-fillers can help them win fights more consistently assuming players are prepared for the temporary setback in terms of resource losses.

3 Combat Width 12

Decently Balanced, With A Slight Disadvantaged In Urban Fights

Despite being so close in terms of numbers to Combat Width 11, a Division of Combat Width 12 immediately performed better in various fronts. While it faces a disadvantage when attacking in Marshes and Mountains from one direction, it doesn’t receive as many penalties in other regions. Its potential performance in Hearts of Iron 4 drastically improves in the Plains and even more in Urban environments, although the latter remains its weakest terrain.

Should players want to maximize Combat Width 12, they can use their presence and accessibility to accommodate different combat situations. Their smaller numbers make them ideal for defense and quick production, allowing players to defend critical chokepoints while reinforcements are on the way. Their nature for easier line stacking and cycling allow them to plug in holes in combat, although players do need to take their easily-destructible nature into account.

4 Combat Width 14

Good Enough If Not Pushing For Width 15

Unsurprisingly enough, the sheer efficiency of Combat Width 15 means its predecessor Combat Width 14 is likely going to perform with similar numbers. Stats-wise, Combat Width 14 does incur slightly more penalties in most terrain, especially Marshes and Mountains, as well as Urban environments. However, this Width outperforms Combat Width 15 in one-directional fights in the same terrain - a mostly negligible stat that players may use in specific situations.

Given its nature as a smaller Division size, Combat Width 14 is best used as more of a defensive measure, as larger Divisions have better offensive stats. Thanks to possessing more Organization, Combat Width 14 shares the advantage of a narrower-width Division being able to hold the line more efficiently. Not to mention, the potential higher Soft Attack of Combat Width 14 Divisions may also deorganize attackers much faster, hence their potential performance as a defensive Width.

5 Combat Width 18

More Penalties Vs Width 15, But Still Manageable

As a narrow-width Division just passing Combat Width 15, it makes sense for Combat Width 18 to possess similar advantages of a smaller-sized Division with some penalties on specific terrain in Hearts of Iron 4 gameplay. It’s in this regard that penalty-distribution in Combat Width 18 is less than Widths 15 and 14, but has harsher penalties in specific directions in terrains (2 Directions in Marsh/Mountain, 1 Direction in Forest/Jungle, 1 Direction in Urban) compared to Width 14.

In this regard, players who want to settle for Combat Width 18 instead of going for Combat Widths 15 and 20 outright can use this Division Width as terrain fillers while they’re still forming their main line. Their smaller numbers allow players to transport and protect supply more efficiently, and their potential cost-effectiveness can help save valuable resources during combat.

6 Combat Width 40

Technical Number Ideal For Large-Scale Urban Conflict

Due to how Urban Terrain already offers +20% Movement Cost on top of -30% Attack and -50% Enemy Air Support, players may as well take advantage of these penalties to opt for a battle based on numbers. This is the underlying logic of Combat Width 40, as its lack of penalty multipliers on Urban Terrain means players can try to go wild with large divisions to devastate enemies in these areas.

Not to mention, the relatively manageable penalties on Plains, Hills, and Desert as well as Marsh and Mountains can make Combat Width 40 a tolerable heavy-hitter in these areas. The increased penalties for Forest and Jungle areas make Combat Width 40 not as practical in these locations.

7 Combat Width 35

Technical Possible Width To Deal With Plains, Hills & Desert

While the Plains and the Lake remain as the more neutral of Terrain types in Hearts of Iron 4 gameplay, the Desert's +5% Movement Cost and +15% Attrition, as well as the Hills' +50% Movement Cost with -25% Attack, seem to be more bearable penalties compared to those possessed by other combat locations. In this regard, players can capitalize on the increased numbers of Combat Width 35 to potentially wreak havoc on enemy forces, at least provided they don't step into Marsh and Mountains due to their innately large penalties.

Among Combat Widths going towards the larger part of the scale (>30), Combat Width 35 makes for a reasonable middle ground, especially for increasing troop numbers. Width 35's relatively manageable penalties mean players can balance these setbacks with the bonuses of division multipliers. With the right division composition, Combat Width 35 may be able to become the player's main frontline or defensive force.

8 Combat Width 18

Secure Defense By Plugging Into Vulnerable Sections

At first glance, players who want high-intensity grand strategy warfare might want to proceed with their Hearts of Iron 4 gameplay with more aggressive strategies. However, those who want to play safe in terms of securing both attack and defense might want to get Combat Width 18 units in reserve.

Compared to other Width setups, Combat Width 18 is more suitable for protective and defensive plays. Their small nature makes them weak in terms of overall firepower, but being cheaper allows them to be plugged into defensive lines and even garrisons more efficiently. Their compatibility across most Terrains due to minimal penalties also makes them suitable for backline plays, especially when players find themselves at a disadvantage.

9 Combat Width 20

Small And Sweet Number For Tactical City Fights

While a game like Hearts of Iron 4 can encourage large-scale conflicts to take areas quickly, players who prefer to play it safe could use Combat Width 20 for a sweet spot in most incursions - especially for Urban Terrain, which generally offers low penalties at the onset. Given the 80/40 setup of Urban Terrain, Combat Width 20 can overwhelm foes with multi-directional strikes. Moreover, the nature of No Step Back wars being won by capturing Supply Hubs can work well with Urban-accommodating units, as many Supply Hubs are often in cities.

Not to mention, the rather low scale of penalties in other areas such as Marshes and Mountains make Width 20 reliable in supporting roles. While its lack of firepower makes it unideal for large-scale conflict, its size should be just right for supporting the backline or even flanks.

10 Combat Width 30

Technical Width To Dominate Forest & Jungle Incursions

Considering the +50% Movement Cost of the Forest and Jungle Terrains on top of the -15% Attack and 0.08 Supply Flow Penalty imposed on combatants, Combat Width 30 seems like a technical sweet spot for Hearts of Iron 4 players who want to dominate a particular Terrain in land combat. At first glance, Combat Width 30 seems to lag compared to higher-number regiments. However, it's in the relative lack of penalties where the Combat Width shines.

Second to Forest and Jungle Terrains, Combat Width 30 doesn't have as many penalties when used in Urban Terrains. Not to mention, it can theoretically perform reasonably well in Plains, Hills, and Desert, as well as the more movement-brutal Marsh and Mountain areas. As such, while Combat Width 30 is again not as efficient as higher-number Widths in terms of overall firepower, building them en masse could give players a more manageable edge in overall combat.

11 Combat Width 25

Technical Ideal For Marsh & Mountain Skirmishes

The high base penalties of Marsh and Mountain Terrains related to Movement Cost (+100% to both), Attrition (+35%,+30%), and Attack (-40%,-50%) make them extremely dangerous for most unit setups in Hearts of Iron 4. This is also why Combat Width 25 is rather practical in these environments, as they suffer the least penalties in these locations. Moreover, their manageable penalties on other Terrains make them a relatively safe "middle ground" between large forces and smaller units, making this a more all-around Combat Width for most players to try.

Of course, this metric is only based on sheer penalties alone, meaning Doctrines, Technologies, and even division composition play a large role in determining the success of Combat Width 25 in combat. Setbacks here include the undeniably smaller numbers of Combat Width 25 compared to other unit compositions, as such making it ideal for them to be supplemented with backup or for them to act as heavy-hitting support.

12 Combat Width 15

Ideal For Non-Specialized Divisions

Fans of Hearts of Iron 4 who want to find an adequate Combat Width to accommodate most combat situations should consider Combat Width 15. This isn't to say that Combat Width 15 can take down most enemies, but this Width has the advantage of having the least penalties for terrain types and attack directions. In turn, the Width is ideal for players who want a safe unit composition to tinker with in situations.

At its core, its non-specialized nature means Combat Width 15 can be converted into almost any combat role. However, Combat Width 15 isn't suggested for large-scale combat incursions due to disadvantages in terms of firepower and defense. In turn, they're not suitable for hard-cementing frontline attacks or pure protections. Instead, the Width is more effective for fortifying defenses or surprise engagements to secure breakthroughs past the enemy's divisions.
