- Module Types
- How to Research and Buy
Researchable modules fall into five types.
Most regular vehicles, except most Tier X and XI ones, have one or more upgradeable modules. Why is upgrading essential?
- Better modules enhance your vehicle's characteristics.
- To move to the next tier, you have to research a certain number of modules of the current vehicle.
- Vehicles with all modules and subsequent vehicles researched acquire Elite status. Combat Experience earned in an Elite vehicle can be either used to accelerate crew training, or converted to Free Experience. Moreover, Elite vehicles have access to Field Modification.
You will need credits and experience to research new modules:
- In your Garage, click
(Vehicle Management) and select RESEARCH. The MODULES tab opens, with the tree of researchable modules for the vehicle displayed on the right side of the screen.
The amount of Combat XP required to research modules is displayed on the unresearched modules. If the module is already researched, its cost in credits will be displayed. - Click the module, then click Research in the lower part of the screen and confirm your action. Now the module displays the purchase cost in credits.
- Click the module again, then click Purchase and mount and confirm your action.
You can sell the previous module at the same time. Otherwise, it will be automatically demounted and sent to Depot.
- Shell Types
- Resupply Ammunition
Armor-piercing (AP) shells are the standard type of shell for most vehicles in the game. They cause damage when they penetrate armor or hit a module.
AP shells are generally suitable for firing at vehicles of the same tier or lower, and at vehicles with moderate armor protection.
Disadvantages of AP shells:
- No damage if they do not penetrate
- Have a high chance of ricochet
- Penetration ability declines at long range
Some vehicles can be equipped with special AP shells with better penetration or higher damage.
High-explosive (HE)shells explode inside the vehicle if they penetrate its armor, causing damage both from the penetration and fragmentation damage, while also damaging modules and crew members. If they fail to penetrate the armor, HE shells explode on the armor surface, causing (at most) a smaller amount damage. HE shells of SPG vehicles can also stun crew members of both enemy and allied vehicles.
HE shells can be a good choice against thinly armored targets, or in high caliber guns and, of course, when playing in an SPG.
Disadvantages of HE shells:
- Low penetration rate
- Low damage if they explode on the armor exterior
- Damage can be fully absorbed by armor or destructible objects on the shell's way
Some vehicles can carry special HE shells with even greater splash damage, and some guns can be equipped with HESH shells with greater penetration.
Armor-piercing composite-rigid (APCR) shells function similarly to AP shells but have higher velocity and penetration.
These shells are highly effective in close combat against heavily armored opponents.
Disadvantages of APCR shells:
- Low effectiveness when shooting at angles or at long range
- High cost
These shells are used as standard ammunition for some mid- and high-tier vehicles.
High-explosive anti-tank (HEAT) shells are a special type of shell. Their penetration is much higher than that of AP and APCR types. HEAT shells don't lose penetration at long range and don't follow the standard principles of ricochet.
HEAT shells are effective against heavily armored vehicles and at long range.
Disadvantages of HEAT shells:
- Often have no effect when hitting armor at high angles
- Detonate instead of passing through destructible objects
- Can often be expensive
These shells are used as standard ammunition for some mid- and high-tier vehicles.
Autocannon shells are a special low-сaliber shell type for vehicles with autocannon and continous fire systems. In the game, these shells are marked with a blue ribbon and come in three types: armor-piercing, armor-piercing composite-rigid, and high-explosive.
The damage and penetration values of each shell are relatively low; however, when a vehicle fires continuously from an autocannon, dozens or even hundreds of shells can be fired. The thinner the enemy's armor, the more shells will penetrate it, and together they can quickly deplete a large amount of hit points.
Autocannon HE shells differ from regular HE shells. They have very low penetration, no fragmentation damage, and no standard splash damage on impact. Therefore, these HE shells are ineffective against thick armor, spaced armor, and tracks. However, autocannon HE shells are highly effective against exposed areas of thin armor, dealing significant damage for their caliber. Even a single burst of HE fire can cause severe damage to lightly armored vehicles, significantly reducing their hit points and damaging modules and crew members.
General disadvantages of autocannon shells:
- Limited effectiveness or complete ineffectiveness against heavily armored vehicles
- Autocannon HE shells don't deal splash or fragmentation damage and are ineffective without penetration
Shells can be bought in the Garage.
- Click on any ammo slot above the vehicle panel.
- Use the sliders to set the number of the shells you want the vehicle to carry.
- Click Apply to confirm the purchase.
Note: At the beginning of the battle, the vehicle is automatically loaded with shells from the first slot. You can change the ammo order in the slots with the arrows 
while purchasing shells.
- Types of Equipment
- How to Buy and Mount
There are four types of equipment:
- Standard equipment can be obtained for credits or earned in in-game events. Standard equipment is divided into classes depending on the vehicle tier on which it can be mounted. In addition to classes, standard equipment is divided into four categories by the characteristics that it improves: firepower, survivability, mobility, and scouting. From Tier VI, one equipment slot is assigned to one of these categories depending on the vehicle. If equipped to this slot, equipment of the corresponding category is more effective. Standard equipment can be demounted and sent to the Depot for gold or with a Demounting Kit.
- Improved equipment is purchased for bonds or can be obtained in in-game events. This type of equipment provides higher bonuses than standard equipment, even when standard equipment is mounted in a suitable category slot. Improved equipment can be demounted for bonds.
- Bounty equipment is available through various in-game events such as the Battle Pass. The basic effect of Bounty Equipment is the same as that of the standard type, but you can upgrade it for credits, making it more effective. Bounty Equipment can be demounted for gold or with a Demounting Kit.
- Experimental Equipment can be obtained by completing missions when participating in certain events. This equipment cannot be destroyed, but it can be disassembled for free. In return, you will receive components that can be used to upgrade or demount it.

Equipment can be purchased in the Garage:
- Select the vehicle on which you want to mount equipment and click on any empty equipment slot on the vehicle panel.
- Click on the equipment you want to buy and mount on your vehicle. It will be displayed in the selected slot.
- Choose the equipment and click Apply.
You can change the equipment order in the slots. Hold down the left mouse button and drag the equipment from one slot to another.
To demount equipment, select its slot and then click 
(Demount). The selected equipment will be sent to the Depot.
- Types of Consumables
- How to Buy and Resupply
Consumables fall into standard and imroved types: Standard consumables improve battle performance and are quite cheap. Improved consumables are far more effective and provide additional bonuses, but cost a significant amount of credits.
The Repair Kit, First Aid Kit, and Fire Extinguisher are reusable during a battle. When activated, the consumable has a cooldown (90 seconds for the standard and 60 seconds for the improved one), after which it is ready for reuse. You will have to resupply the consumable if you use it in battle, no matter how many times it was activated. All other consumables are activated automatically; they provide an effect within one battle and are gone at the end of it.
Learn more about consumables on this page.
You can buy consumables right in your Garage:
- Click on any slot for consumables above the vehicle panel.
- Click on the consumable you want to equip your vehicle with. It will be displayed in the selected slot.
- Click Apply to confirm the purchase.
You can change the consumable order in the slots. Hold down the left mouse button and drag the consumable from one slot to another.
To remove a consumable from a slot, click 
(Send to Depot).
Crew
No vehicle can roll into battle without a crew. A well-trained crew enhances your battle performance and is key to your success on the battlefield.
Crew members get experience after each battle and can learn perks for their specialization. Properly selected perks and their combinations between crew members provide significant advantages in battle.
- Researchable Vehicles
- Premium Vehicles
- Collectors' Vehicles
- Reward and Special Vehicles
Researchable vehicles are the vast collection of vehicles of different nations and types that are available to all players. To research and buy them, you will need Combat or Free XP and credits. Also, these vehicles can be partially or fully researched with vehicle blueprints.
Go to the TECH TREE tab in your Garage to view all the nations and researchable vehicles that exist in the game. Each nation is represented by at least one branch of vehicles from Tier I through XI. On the Tech Tree screen, you can explore vehicle characteristics in detail and see research and purchase costs, as well as buy new modules and vehicles.
Premium vehicles are unique vehicles that you don't need to research. You can buy Premium vehicles for gold or bonds in the in-game Store or buy them for real money in the Premium Shop. You can also get them as gifts, win them in various specials, receive them as rewards for completing in-game missions, or purchase them during short-term events.
Premium vehicles provide a range of benefits:
- Boost Credit and Combat Experience earnings
- Carry Elite status by default, allowing you to accumulate Combat Experience that can be converted into Free Experience
- Allow the option of accelerated crew training
However, for all their economic benefits, Premium vehicles are not invincible and don't have any special advantages on the battlefield. Therefore, to achieve great earnings in Premiums, you still have to be a skilled fighter.
Collectors' vehicles are special vehicles that are available for credits in the in-game Store. They are not bound to the Tech Tree and are available immediately without researching. However, to unlock a Collectors' vehicle for purchase, you have to research at least one vehicle of the same tier in the Tech Tree of the corresponding nation.
Collectors' vehicles have researchable modules available for XP. When all modules are researched, the vehicle obtains Elite status. You can apply Field Modification to Tier VI–XI Collectors' vehicles.
Reward and special vehicles are rare vehicles that are usually obtained in special battle modes and in-game events. Vehicles that were removed from the Tech Tree before Update 1.9 are also special vehicles.
Some reward and special vehicles can be purchased for bonds in the in-game Store, or for credits during short-term special events like Black Market. You cannot purchase such vehicles for real money.
Reward and special vehicles provide the same benefits as Premium vehicles, except for increased credits earned in battle.
