On November 23, 2009, Private Millar demonstrated great heroism during an insurgent attack on Forward Operating Base Wilson, in Afghanistan. With mortar bombs falling around him, he unhesitatingly ran to the impact area to provide first aid to a seriously wounded American soldier. Despite the danger, he remained with the casualty, fully exposed to the attack. Private Millar’s courageous actions under fire allowed for the best possible treatment to his comrade and brought great credit to the Canadian Forces.
