I doubt you can do a "random chance" thing but "In My Mod" <everybody runs away screaming
> the mines do not have built-in cloaking ability - you have to put "Mine Stealth" components on them which do not require normal cloaking tech but instead require mine tech. And there is an added sensor, the Tachyon Sensor IV, which can detect ALL cloaked things, but it is rather expensive to research and build.
