Anyone have a clue what she is saying?

The bright blue bandana gets me. I've heard of wierd shit being used to identify yourself in an attempt to avoid getting fragged, but that thing just yells "shoot me".

On the other hand, I'm sitting in an office and she's not even shaking after this close miss, so...

That said, does anyone know what that orange plate on the PSO1-M2 (?) is, right on the elevation adjustment knob?

Not ISIS....Daesh.

she looks so young; very brave combined with young and possibly naive

You mean 'a soldier'

Geez... that's nuts! On the operations side, position compromised, time to move.

Yeah, that's what I was thinking. I've never been in the military but my first thought was that they should probably move before the enemy starts lobbing mortar rounds or launches an RPG to displace the sniper.

I'm guessing she's actually in shock.

I would be lying on the ground crying and pissing myself at the same time.

looks like a (possible) ricochet to me

Rough translation from a Kurdish redditor named Pelo_o : After talking about enemy sniper's location, she says,"For God's sake, why didn't it hit me?" Taffi Taffi is Arabic for "turn it off". She's telling the cameraman to stop recording.
The Redditor says she was speaking Kurmanji. She sounds like she's firm Qamishli, Syria.
