Better Mechanics : Artillery Reborn

Artillery shaped the battlefield of World War II, but in Hearts of Iron IV its cost, width, and offensive performance often make it difficult to justify.

Better Mechanics: Artillery Reborn is a focused balance overhaul that makes artillery worth building and gives each type a clear role.

No feature bloat or new mechanics. Just better numbers.

The Problem With Vanilla Artillery

• 3-width battalions fit awkwardly into many common division templates and can waste available combat width.
• Its industrial cost often provides too little combat value.
• Low breakthrough makes artillery-heavy divisions fragile on offense.
• Rocket artillery lacks a strong battlefield identity.

What This Mod Changes

Combat Width: 3 -> 2

• All affected artillery battalions use 2 combat width.
• Cleaner templates with less wasted width.

Line Artillery and Motorized Artillery

• Soft Attack: +25%
• Hard Attack: +150%
• Defense: +25%
• Breakthrough: +25%
• Piercing: +100%
• Role: Reliable general-purpose fire support for both defensive and offensive formations.

The hard attack and piercing represent concentrated fire, direct-fire engagements, and specialized ammunition. Artillery can support attacks against armor, but does not replace dedicated anti-tank units.

Rocket Artillery

• Soft Attack: +50%
• Hard Attack: +150%
• Breakthrough: +50%
• Piercing: +150%
• Role: High-impact assault artillery for breaking fortified, concentrated, or heavily equipped formations.

Massed salvos, rapid saturation, and shock make rocket artillery the strongest option for supporting major assaults.

Motorized Rocket Artillery

• Soft Attack: +25%
• Hard Attack: +150%
• Breakthrough: +25%
• Piercing: +150%
• Role: Mobile anti-armor fire support for fast divisions.

Motorized rockets trade some raw assault power for mobility. Both truck-towed and vehicle-mounted rocket battalions use this profile.

Historical and Gameplay Rationale

• Artillery was central to suppression, defense, and offensive preparation.
• Conventional guns threatened armor through concentrated fire, direct fire, and specialized ammunition.
• Rocket artillery traded precision for rapid saturation and shock.
• These bonuses represent battlefield influence, not the literal performance of every gun or rocket.

Design Principles

• No hidden cheats or country-specific advantages.
• No scripts, new equipment, or technology changes.
• Bonuses scale with existing progression.
• Dedicated anti-tank units remain the specialized answer to armor.

• Does not change equipment files or technology trees.
• Does not add new unit types or mechanics.
• Does not change AI behavior.
• Does not modify support artillery companies.
• Does not rebalance anti-tank or anti-air battalions.
• Does not rebalance self-propelled artillery.

• The AI is not taught to redesign divisions around the new balance.
• Mods replacing the same artillery file can override these changes.

Compatibility

This version is designed for The Road to 56.

Compatible with mods that do not replace

. Major total conversions and unit overhauls may conflict.

Load Order:
Place this mod below other artillery mods if you want its values to take priority.

Expected Gameplay Impact

• Artillery-heavy divisions become viable in offensive operations.
• Rocket artillery becomes the premium assault option.
• Motorized rockets provide useful support for fast formations.
• Combined-arms designs are rewarded over pure infantry spam.
