In late 2010, Newsround travelled to the Afghan capital Kabul to find out what it was like to grow up in a country scarred by war.
Now, Newsround's Ore Oduba has journeyed to the heart of the warzone - the southern province of Helmand, where British troops are stationed along with the Americans - to find out why we are there, and what we are doing in the country.
