I′m in Stealth Mode and the Enemy see my Nickname over my Head!
If this is not a cheat code, what must i do to see this too?
I used all Modules and i didn′t get this.
Cheat or not, that will be the question!

just checked.
I were aiming at cloaked guys back(enemy) over 4-5 seconds with scope, and without it. No nick detection. Then I've took his badge)

This is not a bug or a cheat.

If you point your binocular at someone (stealth-ed or not) you and everyone in your team will see his name with a red arrow above his head for a short while.

Just remember that while using the binocular you can't use your weapons so you are pretty much a sitting duck...

I got this module you mean.
But it′s not that i meant.
They see nothing just my Nickname.
The stuff with the red arrow is a module, doesn′t let see you the nicknames.
So what is it?

Nicknames appear on everyone in sight in killcams, and since you know what he's seeing I'm guessing your watching killcams.

I do not think that someone using a binocular in MP, afraid to be quickly killed on the spot till they're using it.

Seems truly to me.
