The first instalment of the five part series, called 'Ross Kemp in Afghanistan', was watched by 941,000 viewers between 9pm-10pm, according to unofficial viewing figures.

Kemp trained with soldiers of the Royal Anglican Regiment before following them to Helmland where Britain has 7,000 troops, and in later episodes is seen coming under fire from the Taliban.
