: Shell tooltips were updated during this period to provide clearer data on how projectiles interact with various obstacle thicknesses, which directly influenced how players engaged these new fuel tank modules.
In the (October 2014), the "All Vehicles Excess Fuel Tank" feature introduced a significant change to how ground vehicles handle fuel. Prior to this, fuel tanks were often generalized components, but version 1.43 transitioned them into discrete, calculated modules. Feature Overview All Vehicles Excess Fuel Tank v1.3 1.43
: By treating fuel tanks as individual components, their specific location and current fuel level began to play a more realistic role in the vehicle's damage model. A hit to an "excess" or external fuel tank could cause a fire or explosion, but its separation from the internal crew compartment could sometimes mitigate catastrophic failure depending on the vehicle's design. : Shell tooltips were updated during this period
: Fuel tanks and ammunition loads were separated and calculated as distinct modules for all ground vehicles. Feature Overview : By treating fuel tanks as
This system has since been refined in subsequent patches, but the 1.43 update remains the foundational moment when fuel tanks moved from abstract health bars to physical, targetable components. Update 1.43 - War Thunder Wiki
