Military Working Dogs have a long history in the United States dating back to World War II.   

About 2,000 of these working dogs confront danger beside American soldiers, largely in the Middle East.   With noses that detect scents up to a third of a mile away, many sniff for explosives. Their numbers have been growing about 20 percent a year since the terrorist attacks of 2001.  

  The remembrance poppy has been used since 1920 to commemorate soldiers who have died in war. They were first used in the US to commemorate soldiers who died inWorld War I (1914–1918). Today, they are mainly used in current and former Commonwealth states to commemorate their servicemen and women who have been killed since 1914. In those states, small artificial poppies are often worn on clothing on Remembrance Day/Armistice Day  (11 November) and in the weeks before it.
