Looks like a torniquete on that limb, and based on its orientation it may be pulped (sadly I’ve seen that from concussive blasts). I think she was putting a gasket bandage on the chest in case of sucking chest wound. Not a happy day, hope they made it to the rear.

That was a gnarly wound, I hope they’re alright

They are so brave. Wish them all the very best.

Unbelievably badass.

I hope I never have to be this brave.
