On January 18, 2006, Corporal MacDonald, a member of the improvised explosive device disposal team, responded to the threat posed by a vehicle loaded with improvised explosive devices in Afghanistan. In a very dangerous environment, he worked over 14 hours under difficult conditions to avert the potential death or injury of coalition forces members and civilians. His exceptional stamina and determination exceeded what is expected of improvised explosive device operators. Corporal MacDonald’s perseverance and his devotion to duty resulted in the largest recovery of an operational device by Canadians.
