Royal Welsh Afghan tour

Three Welsh Guardsmen have been killed in Afghanistan this year by rogue local police and army personnel. And the so-called 'green-on-blue' attacks have now claimed the lives of 50 international soldiers.

As part of our series of reports from the front line, one serving Welsh guardsman has called on the Government to pull British troops out of Afghanistan, saying the campaign is a 'futile waste of life'.

We've been speaking to him, and to other troops from Wales, involved in training the Afghan forces in the Nad Ali district of Helmand Province.

Over the last two nights we've been following the work of Welsh soldiers who are based in Afghanistan.

But of course there are also many civilian workers there, helping to support the country as well - and one of the most senior of them is a development expert from Cardiff.

In the final of a series of special reports for Wales Tonight, Gwyn Loader has been to meet her and discover more about the differences being made in Helmand Province.

The last six months have seen five Welshmen killed in Afghanistan as they prepare local Afghan forces for the withdrawal of international soldiers.

In the first of three special reports, our reporter Gwyn Loader has spent a fortnight on the frontline living with soldiers from the Royal Welsh and Welsh Guards Battalions. At their forward operating base in the Nad-e-Ali area of Helmand Province.

Gwyn takes a look at the changing role for British troops in Afghanistan as they complete their final tour of Afghanistan.
