Engineering vehicles can enter minefields without setting off the mines which seems kinda odd.
Also, since mines are neutral they make cloaked units appear if one gets inside the decloak radius. This could be used (abused?) as a crude mine detector.
Mines iirc can easily be found anyway – the minefield sign unit isn’t cloaked, you need only get within LOS of an enemy minefield and if you look closely will be able to see the mine sign.
Engi vehicles don’t detonate mines I assume because they’re made to eventualy remove them – however, they shouldn’t. We should have dedicated mineclearing vehicles… for the Brits atleast.
