Captain Ray Wiss is an emergency medicine specialist from Sudbury, Ontario, and a member of the Canadian Forces Reserves. From November 2007 to February 2008, he served with Task Force Afghanistan. Very unusually for a physician, he spent virtually his entire tour in the combat area, at Forward Operating Bases (FOBs) in Kandahar province. While in Afghanistan he kept a diary, which he emailed back to Canada to explain, to his family and friends, what he was doing.
