Sapper Matthew Garey has been awarded the Queen's gallantry medal for his "awe-inspiring courage" and "extraordinary" conduct as he battled to clear a route damaged in a fatal attack by an Improvised Explosive Device in Helmand Province.
He placed himself in harm's way for five hours as he painstakingly searched for a sign of an IED ahead of his team, with ultimate success.
The Ministry of Defence said: "Finding a deeply buried command wire in his path provided the final piece of the jigsaw that told the story of a complex, multiple IED attack planned to hinder the freedom of movement along the route."
Three soldiers have received prestigious Army awards for their selfless acts of bravery which saved the lives of comrades in Afghanistan.
A soldier who led a bayonet charge through insurgent enemy fire and another who fought on after being shot in the head have been honoured.
