You’re running out of options. To the right, there’s a house where one of your friends is lying injured; he is just visible in the shadows created by the harsh sun streaming through an empty window frame. To the left is a small shack you know holds two, maybe three heavily armed enemy insurgents. The shattered doorway in front of you is your only way out, and you only have two bullets. Two chances, to save yourself, and your friend. The adrenaline is off the charts.
