When an enemy vehicle runs over and is destroyed by an anti-tank mine, the AI infantry, even those that are not grouped with the vehicle that was destroyed, will become aware of your location. This occurs regardless of your location at the time the vehicle runs over the mine.
- Legacy ID
Place AT mine along a road that an enemy vehicle will travel on.
Wait for enemy vehicle to run over the mine (watch cool explosion).
At this point, if you are in line of sight of enemy infantry, they will begin to fire at you.
Repeat, but choose a different location to wait for the vehicle to run over the AT mine.
The enemy infantry will know your new location.
This behavior can be tested using command knowsAbout https://community.bistudio.com/wiki/knowsAbout
The value set by explosion of mine of unknown target is 1.5, which is different from 4.0 when enemy knows all about you (including your position). In game this equals to the AI knowing about someone planting the mine but not knowing where exactly that someone is. You can check it visually by looking at the enemy near the explosion area: they will start searching the bushes not go towards you (if you are hiding behind some far away obstacle).
Please check if you observe the same behavior or attach a mission where you prove me wrong.
