New Invisibility Glitch Discovered by ME!!

I found an epic invisibility glitch on Uncharted 3!!

Heres what rules apply when you are invisible:
People can see your name unless you have the booster Cloaked equipped.
Enemies can shoot and punch you if they somehow know where you are.
You can shoot and punch people.

You will temporary or completely go back visible if you:
Taunt
Have the riot shield equipped (You can have it on your back but not hold it in front of you)
Roll

You can still climb, run and shoot people while invisible.

Now how to do it:

Get a riot shield then go in cover and aim at the same time.
