Spotted Extended mod is designed to indicate which enemies have been spotted by the player.
Estimated spotting damage ia also provided but be warned, display and calculation of spotting damage may not be accurate!
The calculation will be improved in newer versions, because the server does not provide data on spotting damage until after the match ends.
Mod is displayed by default on the mini-map, with icons for highlighted enemies and there is also an additional indicator on enemy tanks in battle.
Disclaimer: Some mods can be regarded as cheat or illegal on some servers.
