So you boot up Hearts of Iron IV. You design the perfect armored division. You click on support companies. And… your Flame Tank Support Company is not there. Panic sets in. Did the game bug out? Did you miss something? Relax. This guide will walk you through it step by step. Simple. Clear. No stress.
TL;DR: If Flame Tank Support is not showing, you likely missed a requirement. You need the right DLC, the correct tank design with a flamethrower module, and the proper doctrine and tech. Make sure the tank is marked as a flame tank role. Check division designer filters. Most issues come from missing one small step.
First, What Is Flame Tank Support?
Before fixing the issue, let’s understand what it is.
The Flame Tank Support Company is a special support unit. It gives bonuses in forts. Cities. Forests. Jungles. It is amazing for pushing through tough defensive terrain.
It does not act like a full tank battalion. It is a support company. It boosts your division without increasing combat width by much.
It was added with the No Step Back DLC. That detail is very important.
Step 1: Do You Have the Right DLC?
This is the most common problem.
If you do not own No Step Back, you cannot use Flame Tank Support. Period.
To check:
- Open Steam.
- Right-click Hearts of Iron IV.
- Click Properties.
- Go to DLC.
- Make sure No Step Back is enabled.
No DLC? No flame tanks. Simple as that.
If you do have it, move to the next step.
Step 2: Did You Research the Right Tech?
Even with the DLC, you must unlock the tools.
You need:
- Basic Tank Chassis (Light, Medium, or Heavy)
- Engineer Company tech
- Flamethrower module
Go to the Armor research tab.
Research a tank chassis first. Without a chassis, there is nothing to modify.
Then open the Tank Designer.

Step 3: Did You Add a Flamethrower Module?
This part confuses many players.
You do not automatically get flame tanks.
You must create them.
Inside the Tank Designer:
- Select a tank chassis.
- Click on a weapon slot.
- Choose a Flamethrower.
If you do not see a flamethrower option, check:
- Did you research it?
- Are you using a compatible chassis?
Once the flamethrower is installed, the tank is not done yet. There is one more critical step.
Step 4: Set the Tank Role Correctly
This is the hidden trick.
After adding the flamethrower, look at the top right of the designer. You will see a Role dropdown.
You must select:
Flame Tank
If you do not change the role, the game treats it like a normal tank. It will not unlock the support company.
This is where most players fail.
No role change. No support company.
Step 5: Save and Produce the Tank
After setting the role:
- Click Save.
- Rename it if you want.
- Start production in the Production tab.
You do not always need thousands in stock. But you do need some in production or storage for the option to appear properly.
If you designed it but never built it, things may not update.
Step 6: Check the Division Designer Again
Now go back to:
- Recruit & Deploy
- Edit your division
- Click an empty support slot
You should now see:
Flame Tank Support Company
If it still does not appear, do not worry. Keep going.
Step 7: Check Special Limitations
There are a few extra rules.
1. You Cannot Add It Without an Empty Slot
Support companies are limited. If all slots are full, you must remove one.
2. Some Special Divisions Have Restrictions
Certain template types may restrict support options depending on mods.
3. Are You Using Mods?
Mods can break things.
If you are running overhaul mods like:
- Kaiserreich
- Millennium Dawn
- Black ICE
They may:
- Disable flame tanks
- Change tech requirements
- Move modules in the tech tree
Try launching the game in vanilla mode to test.
Step 8: Check Your Game Version
Outdated versions cause problems.
To check:
- Look at the main menu corner.
- Confirm you are on the latest patch.
If not:
- Verify game files in Steam.
- Restart Steam.
Corrupted files can hide features.
Step 9: Make Sure It Is Not Filtered Out
This sounds silly. But it happens.
In the Division Designer, some UI scale settings or mods can visually hide certain options.
Try:
- Scrolling carefully
- Changing UI scale
- Restarting the game
Sometimes the button is just out of view.
Common Mistakes Recap
Let’s simplify everything.
If Flame Tank Support is missing, it is usually because:
- You do not own No Step Back
- You did not research a tank chassis
- You did not add a flamethrower
- You forgot to change the tank role
- You did not start production
- A mod changed something
Most of the time, it is the role setting. That tiny dropdown defeats generals daily.
Why Use Flame Tank Support Anyway?
Since you are going through the trouble, let’s talk strategy.
Flame Tank Support gives:
- Attack bonuses in forts
- Attack bonuses in cities
- Attack bonuses in forests and jungles
- Extra armor stats for the division
It is incredible for:
- Pushing the Maginot Line
- Urban fighting in Stalingrad
- Breaking jungle defenses in Asia
They are situational. But when used correctly, they are brutal.
Light vs Medium vs Heavy Flame Tanks
You can use different chassis types.
Light Flame Tanks
- Cheap
- Fast to produce
- Lower armor
Great early game option.
Medium Flame Tanks
- Balanced stats
- Better armor
- Solid mid-game choice
Heavy Flame Tanks
- Expensive
- Very strong
- Overkill sometimes
Most players prefer light or medium for support companies. Heavy can be too costly for minimal gain.
If It Still Does Not Work
If you followed every step and still see nothing, try this checklist:
- Disable all mods
- Verify game files
- Start a fresh save
- Test with Germany in 1939 start
Sometimes old saves carry strange bugs.
Testing in a fresh vanilla game helps isolate the issue.
Final Thoughts
Flame Tank Support not showing is almost never a true bug.
It is usually a missed step.
HOI4 has many systems stacked together. Research. Design. Production. Roles. If one link in the chain is missing, the option will not appear.
But now you know the full chain.
Get the DLC. Research the chassis. Add the flamethrower. Change the role. Produce the tank. Add the support company.
That is it.
Now go set Europe on fire. Strategically, of course.
