How to Mount Equipment
Equipment is available in pairs in nine slots. These slots are grouped by type of improvement (the way they affect the tank): combat power, vitality, and specialization. Each type of improvement has three possible slots.

A newly purchased tank has all equipment slots locked. To mount an upgrade, the corresponding slot must be unlocked.
Unlocking equipment slots takes credits. Once paid for, they unlock instantly, and the cost to unlock them depends on the slot level and the vehicle Tier:
| Tank Tier | Level I slot | Level II slot | Level III slot |
|---|---|---|---|
| I | 100 | 200 | 300 |
| II | 200 | 300 | 400 |
| III | 400 | 500 | 600 |
| IV | 4000 | 5000 | 6000 |
| V | 40 000 | 50 000 | 60 000 |
| VI | 100 000 | 120 000 | 140 000 |
| VII | 150 000 | 170 000 | 190 000 |
| VIII | 200 000 | 225 000 | 250 000 |
| IX | 250 000 | 275 000 | 300 000 |
| X | 300 000 | 350 000 | 400 000 |
To unlock the equipment slot, you need to select it in the equipment window and tap Unlock (in the bottom right corner of the equipment window).
Equipment and Bonuses
Here are the bonuses that various equipment offers.
There are two types of equipment for every slot. You can choose only one.
Why is this? First, when you need to choose from two equally tempting options, you'll start carefully studying the characteristics and features of each particular tank. And secondly, this approach will prevent making your vehicle "imba": equipment offering similar bonuses is usually located in the same slot, and you can’t mount them all at the same time.
Combat Power
This type of equipment affects the gun characteristics in various ways.
Level I Slot
This is the only slot with contents that can vary for different vehicles: in some cases you'll have Ventilation, in others—Rammer.
- Option 1: Improved Ventilation

Ventilation is available only for "drummers" and vehicles with machine guns. For other vehicles, this slot offers the Rammer.
+5% to all crew skills
- Option 2: Gun Rammer

The Rammer is available for vehicles with conventional guns and also for open cabins. For other vehicles, this slot offers Ventilation.
-7% to reload time
- Option 3: Calibrated Shells
This equipment increases armor penetration:
- +5% for AP shells
- +5% for ARCR shells
- +10% for HEAT shells
- +10% for HE shells
Level II Slot
- Option 1 :Enhanced Gun Laying Drive
+10% to aiming speed
- Option 2: Supercharge
+30% to shell velocity
-50% to armor penetration decrease with distance
Level III Slot
- Option 1: Vertical Stabilizer
+15% to accuracy when moving and during tank and turret movement.
- Option 2. Refined Gun
-10% to dispersion at 100 meters
Vitality
The tank with this equipment will receive fewer critical hits, survive longer, and repair faster
Level I Slot
- Option 1. Improved modules
+10% to track, fuel tank and ammo rack protection
-20% to damage from ramming - Option 2: Defense System
-10% to the chance of engine damage
-8% to the chance of crew injury
-7% to the chance of ammo rack explosion
Level II Slot
- Option 1: Enhanced Armor
+4% to hull and turret armor
- Option 2: Improved Assembly
+6% to vehicle durability
Level III Slot
- Option1: Enhanced Tracks
Enhanced Tracks automatically repair tracks to fully restore track HP (without using the Repair Kit). This upgrade does not speed up suspension repair.
Unless the equipment is mounted, the hit and repaired track is highlighted in yellow. It will be operational, but with lower durability, and can be destroyed more easily. - Option 2: Toolbox
+30% to repair speed
Specialization
Here you have to choose between viewing range and concealment, or speed and maneuverability, as well as between different bonuses to consumables' effects.
Level I Slot
- Option 1: Improved Optics
Bonus to viewing range (but not more than 500 metres):
+5% for tank destroyers
+7% for heavy tanks
+10% for medium and light tanks - Option 2: Camouflage Net
-3–7% to the visibility of moving vehicles
-6–14% to the visibility of the vehicles stationary for more than three seconds
Bonus to concealment depends on the vehicle class.
Level II Slot
- Option 1: Improved Control
+10% to the top traverse speed of the vehicle
- Option 2: Engine Accelerator
Bonus to acceleration:
+5% for medium and light tanks,
+7% for heavy tanks and tank destroyers
Level III Slot
- Option 1: Consumable Delivery System
+15% to consumables cooldown speed
- Option 2: High-End Consumables
+30% to consumables duration (Engine Power Boost, Adrenaline)
A tank competently "stacked" with equipment across all nine slots significantly improves its performance. Cumulatively, these characteristics add up to being much better than those of the same tank with the "old" equipment.
Remember: there is a wealth of combinations of new equipment (512 options!), and once you unlock the slot, you can switch equipment whenever you feel like it.
