Introduction
War Thunder is a unique blend of realism and dynamic battles. However, the current game system lacks deeper interaction with vehicles on the battlefield. I propose implementing a “field modular upgrade” mechanic — the ability to dismantle parts from destroyed enemy vehicles and install them on your own vehicle directly during battle.
Mechanics
A player or allied light vehicle approaches a destroyed of an enemy tank and initiates the process of replacing one of the modules:
Gun — changes weapon parameters (caliber, penetration capability, reload time depending on the turret). Shooting is unavailable during installation.
Turret — changes rotation speed, firing arc, and protection level. During installation, aiming and turret rotation are impossible.
Engine — affects speed, torque, and mobility. Movement is impossible during installation.
Tracks (optional) — restore maneuverability but temporarily block control.
Each installation takes from 30 to 60 seconds depending on the type and complexity of the module. During this time, the vehicle is completely vulnerable — no movement, firing, or control. Only one module replacement is allowed per battle, and only from enemy vehicles.
Restrictions and Balance
The mechanic is available starting from Rank II to avoid situations where, for example, a BT-7 gets a 75mm gun.
Each module must be physically compatible with the vehicle:
Small hulls (M22, BT-7) cannot receive heavy turrets or guns.
If the module does not fit by weight or size — installation is forbidden.
The number of modifications is limited to one module per battle.
The installation process carries risk — the player becomes an easy target.
Modifications should be visually reflected so other players can recognize and react accordingly.
Role of Light Vehicles
Light vehicles gain a new role — field engineer-mechanic:
Tow wrecked vehicles to allies.
Dismantle and install modules.
Serve as support class on the battlefield: not only reconnaissance but also technical support.
Examples
Tiger II with IS-4 engine, Leopard 1 gains better dynamics.
Panther G, A, F, D, 2 with Sherman Jumbo turret changes protection and firing parameters.
IS-3 with PaK 44 L/55 gun — new penetration.
Advantages
More dynamic battles: even damaged vehicles can “come back to life” and rejoin the fight.
Encourages survival: the player does not just “lose a tank” but plans actions ahead.
Develops team interaction: light vehicles become key players in support.
Deeper gameplay: engineering ingenuity becomes an important combat trait.
Conclusion
The proposed combat modular system is a new level of tactical gameplay that can be implemented as a separate mode or temporary event without harming the main game balance. It allows development of engineering interaction, stimulates tactical thinking, and opens a new role for vehicles.
