Are the mines invisible to enemy players (excluding operatives) and only disarm-able by an engineer after an operative has spotted them OR can all players see them and operatives only put them on the mini map; engineers can disable them at any time.

I think you nailed it. Engineers can lay mines and see which ones they've lain; Operatives can see them and reveal them to everyone by iron-sighting them; and enemy Engineers can disarm them once they've been spotted by the Operative.

I'll have to look this up!

I'm not sure if they're flat out invisible - I think they're slightly visible, but I don't remember any official word on that.

I think everyone can see them, but operatives can mark them to make them more visible, and engineers can defuse them.

Hmmm i think that's about right....wow I hope it's not D:

Pretty sure it's this.

Operatives can mark the mines by ADS-ing on them for a bit, which them marks them on allies' radar and gives Engineers the optional objective to disarm it.

Dont flame me for this just how I understand it
Everyone can see them just watch ur step
Operatives see them like with the Hacker perk in COD, but can mark them on the mini map for everyone to avoid
and engineers are the only one with can disarm them

There was another post on this. http://www.gamesas.com/index.php?/topic/1183179-hidden-enemy-mines/page__st__60__p__17554992__hl__invisible+mines__fromsearch__1#entry17554992

Think the conclusion was that mines are invisible to all but Operatives.

I think everyone can see them but Operatives point them out and they highlight red so they're easier to see and may or may not show up on the mini map.

Heres what I know about mines so far..


1. Engineers plant them, Engineers defuse them.

2. Operatives can spot mines, but cannot defuse them. When spotted, a mine has a bright red mark over it.

3. You step on a mine and your stuck. Move one inch and you'll get blown to bits. A friendly engineer will need to come to your aid and defuse the mine.

4. Everyone can see mines. However, they are slightly harder to spot with classes other then Operative.

Hope that helps.

I haven't seen any confirmation of this point anywhere. Some people have watched footage where someone explodes and dies without us seeing anything thrown their way, which could be a Soldier explosive thing or a mine, so it's not very conclusive. There's also the Get Smart video which explains how Operatives can mark mines, but it doesn't confirm if they're invisible or only partly so. Either would work, as long as they're very limited visibility.
