Scots soldiers are playing a key role in the transfer of security in Afghanistan to Afghan forces.

British forces are due to withdraw from Afghanistan by 2014, but many of the 10,000 soldiers deployed there may be brought home in little more than a year.

BBC Scotland's Cameron Buttle has been following 3 Scots, the Black Watch, in Helmand.
