On October 3, 2006, Sergeant Hermiston, serving with the Intelligence Surveillance Target Acquisition and Reconnaissance Squadron, 1st Battalion, The Royal Canadian Regiment Battle Group, in Afghanistan, was among the first to come to the assistance of an observation post which had been attacked and was still under effective and sustained enemy fire. Without concern for his own safety, he quickly dismounted from his vehicle to assist in the treatment and extraction of the wounded. Sergeant Hermiston’s completely selfless act under fire, imbued by quick thinking, courage and dedication, contributed to saving the lives of many of his fellow soldiers.
