On September 3, 2008, during an insurgent ambush in the Zharey district of Afghanistan, an anti-tank round destroyed a light armoured vehicle, resulting in numerous serious casualties. While exposed to sustained enemy fire, Master Corporal Bursey repeatedly returned to the vehicle, in which ammunition was exploding in the ongoing fire, to help extract and tend to the casualties. Master Corporal Bursey’s composure and decisive actions ensured critical care for the casualties until their evacuation.
