It's snowing at magic hour. You and your recon partner lie motionless on top of an embankment overlooking an enemy camp, encased in a cold blanket of ice and silence. Your gloved finger hovers over the trigger. You stare down your sight and track one of the guards. With a deep inhale, the world stops as your expertly executed bullet sails through the air. As your target’s skull explodes in a cacophony of bone and blood and brains, your exhale turns to steam against the frigid air and all hell breaks loose.
