Can anyone confirm whether or not the AI in the campaign can see the laser sight coming off of the player's gun when cloaked? Is it visible to other players in multiplayer? I would like to use it, but I can't really tell if the AI is picking up on it or not.

I wonder this too. They don't seem to react though, but I'm not sure.

AI in single player do not seem to respond to the laser sight from what I have seen. In multiplayer I have seen the laser sight on cloaked team mates giving away their position though, not sure if the opposing team can see it from a cloaked player, but I know I sure could.
