Corporal Beaulieu was the gunner on board a light armoured vehicle when, on October 5, 2007, during a combat logistic patrol in Afghanistan, the vehicle was severely damaged by an explosive device. Although he was injured and under sustained enemy fire, Corporal Beaulieu dismounted the vehicle and manually engaged the enemy, exposing himself to great peril. His heroic actions contributed to neutralizing the insurgents and saved the lives of many members of his platoon.
