Legacy.com has done a wonderful service to our troops who have died in this war and to their families.  You can find all those who have died to the most recent.  Use their search engine to find the Soldier, Sailor, Airman or Marine by name or other options.  You will find those who have died non-combat deaths, but must know their name or date or something about them to find their obituary.  Here is the home page for Legacy.com Soldiers: http://www.legacy.com/Soldiers.asp
