Between December 2009 and 2010, BBC News followed the progress of four soldiers from the Queen's Royal Lancers from basic training to deployment in Helmand province, Afghanistan.
Filmed by the soldiers themselves and army camera crews, as well as by the BBC, the footage captured everything from the shock of coming under fire to coping with harsh conditions.
In this video, Trooper Ian Baird explains what it is like to come under enemy fire, with footage from soldier headcams.
