@Sludig: For Full Defense, you'll need to roll your Reaction (4) + Gymnastics (2) + 2 Partial Cover = 8 dice to reduce the net hits of Guard1. Then you'd need to soak the Physical damage [Body (4) + Armor (8 ) - AP (1) = 11 dice]. You got some decent dice, so you could do it!
If he shoots at me, I think I'm fragged.
