Jackson:3
Many many people with gauss rifles:Jack's wings.
And a signifigant amount of his blood. You seem to have forgotten that those wings weren't made of plastic. He had major arteries and veins going through them. you do realize Jackson is bleeding to death, right?
Yep!...I just hope to have enough time to retreat to a safe area and chuck all my non lethal grenades...then maybe create an opening for the rest of the team if I can.
You know, if one of those non lethal grenades is a goop grenade, you might be able to activate it near yourself to stop the bloodloss. Of course, you'll be immobilized and without arms, but at least you won't be dead.
...Also, how are you chucking grenades if both your arms were turned into wings and then turned into mush?
With his teeth obviously: he bites the lever, uses his tongue to pull the pin, and then shakes his head to throw it. 
Nah, obviously he just stares it down until it throws itself of it's own accord.
