If there's stealth, radar is useless (and vision reveals it anyway.)
If there's cloak, both radar and vision is useless. So no idea how vision is going to help with a mole, since my understanding is that it is cloaked.
Wrong.
Stealth and Cloaking are two separate countermeasures. Stealth defeats radar and Cloaking defeats vision. A unit which is cloaked but not stealthed will be invisible, but detectable by radar. So if you ever see a grey unknown contact in your field of vision - you know it must be cloaked. If you don't have radar, it could be right next to you and you'd never see it.
Stealth on the other hand, it to prevent long ranged contacts. It allows your units to avoid detection as they close range. But will not prevent them being targeted when seen.
