Sometimes in World of Tanks on the Xbox 360 edition you get detected and an alert appears on the bottom of the screen. If you hide then the icon disappears.
You remain still some time visible to the enemies or you instantly disappear to their vision when this happens?
Best Answer
The alert just tells you that you've been spotted by an enemy tank. There is no event tied to when you are no longer spotted, so the icon disappearing does not mean you are no longer seen by the enemy.
However, the alert event trigger will reset if you are not spotted by the enemy for ~5 seconds, and trigger again next time you are spotted.
