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 under constant fire from the enemy, Corporal Ejdrygiewicz worked to extract the injured from the vehicle, in which ammunition began exploding, while alternately providing suppressive fire against the insurgents. Corporal Ejdrygiewicz’s selfless courage under fire was pivotal to the protection and treatment of casualties.
