Jack smirked under his helmet as he scoped in on a target known as Serenity. She had her back to his location. Jacks finger moved to the trigger. He had concussion rounds loaded. They aren't lethal but still back one hell of a punch. He aimed at the back of Serenitys neck. A shot there would not only get a knock out but it was part of the spine and the shock from impact would leave her paralyzed for several hours. Jack zoomed on the spot and pulled the trigger sending the round straight for Serenity. If the round hit, it would be an easy knock out. Right after he pulled the trigger, he raced to the location still cloaked so that if it hit her, he could grab her before her team did.
