Better Mechanics : Combat

Forget everything you knew about Hearts of Iron IV combat.

This mod fully reworks land, air, and naval defines and mechanics for a faster-paced, tactically rich, and historically grounded combat experience.



✳️ Tanks Matter Again

• Armor vs. piercing now uses a tiered, realistic model — no more binary logic.
  
• Heavy tanks shine in fortified breakthroughs.
  
• AT and CAS are reliable counters — combined arms is king.
  
• Armor deflection and resistance make tanks tough, not invincible.

✈️ Air Combat Rework

• Night CAS buffed — no more timezone RNG.
  
• Training accidents and XP loss rebalanced — air superiority has a cost.
  
• Logistics strikes actually matter now.
  
• Anti-air placement and stats have real impact.
  
• Plane stats maxed to 200+ — you can finally feel the difference.

⚓ Naval Combat Revamp

• Deathloop battles fixed — naval fights now resolve properly.
  
• Carrier spam controlled via stacking penalties and strike balancing.
  
• Sub spotting, torpedo logic, and evasion all improved.
  
• Shore bombardment capped at 35% — no more insta-wipe invasions.
  
• Naval AA now scales to reality — up to 75% air damage mitigation.

🪖 Division Design + Military XP Rebalance

• XP costs reduced: 4 for battalions, 8 for support, 12 for regiments.
  
• Army/Navy/Air XP caps raised: 950 / 550 / 675.
  
• Training gives solid XP (at a cost).
  
• Leader XP gain is faster.
  
• Min deploy training: 40% — green spam punished.

🎯 Combat Mechanics Overhaul

• Battles focus on organization damage over raw HP.
  
• Reinforcement chance set to 1.5% — smooth flow, no gaps.
  
• Combat width penalties softened — no more division Tetris.
  
• Tactics/recon/initiative are actually impactful.
  
• Supply & terrain scale correctly — bad logistics = bad outcomes.

🧠 Surrender + War Score Logic Rework

• Peace conference weight now favors damage + territory, not casualties.
  
• Surrender level tweaked — no more Vladivostok world tour to cap the Soviets
  
• 75% of equipment + fuel recovered on capitulation/annex.

📦 Supply, Logistics & Infrastructure

• Out-of-supply penalties are punishing:
  –65% speed, –50% org regen, +10% attrition
  
• 4-day supply grace makes fighting feasible but risky.
  
• Air supply tweaked (5% conversion rate).
  
• Logistics strikes rebalanced — trains/trucks now matter.

🧪 Experimental Tweaks

• Minimum 4-hour combat duration — no ping-pong fighting.
  
• Withdrawal speed buffed, movement flow improved.
  
• Dig-in speed/cap reduced (1.5 speed, cap 8).
  
• Combat overwidth penalties halved, cap at –50%.
  
• XP, bombing accuracy, and equipment conversion rebalanced.
  
• Non-core supply flow nerfed (–0.8 modifier).

🧬 Realism & Cleanup Fixes

• Scorched Earth costs 20 CP — use it wisely.
  
• Captured equipment logic restored — 10% gear retained post-battle.
  
• Conversion IC costs lowered: 5% naval, 15% land.
  
• Naval positioning system improved (detection, screening, AA).
  
• Field XP systems rebalanced — no more infinite farm.

So in theory, a United China should hold against Japan just fine in 1936 start and push a tiny bit at the very start. But if China decides to try to unite China, it won't do as well. It should be able to hold in 1939 as well.
I will continue to make changes. If you have any suggestions or good potential ideas, just head over to Discord, and please do tell!
