Woods could have survived by using Kravchenko as a shield. The grenades were strapped around Krav's chest, but Woods was behind him. So, Krav could have absorbed the most of the blast. Either that, or he just fell short and didn't get affected.

But what I REALLY want to know: If Mason had to go back the way he came, how did he not notice Woods?
