I came across these articles written by Russell Storring. He is a sergeant with the Canadian Army, and has been a signals operator for the 17 years he has been in the military. He completed his third tour of duty in Afghanistan in November 2008, having served there previously in 2005 and 2003. He also served with the UN in Rwanda in 1994. His columns give a first-person account from the field of the life of a soldier.
I can't imagine all he has been through and all he has seen in his various deployments overseas.
