Don't make the assumption that everything air-powered is nonlethal. Indeed in history we find: "In the late 1700's, powerful pneumatic guns even found their way into the ranks of the military.

All surviving accounts indicate that the Austrians used those airguns with deadly effectiveness against Napoleon's army. So feared, any Austrian soldier captured with an air rifle was summarily executed as an assassin!" (http://www.airguns.net/general_airgun_history.php)
