Jane Duffy, mother of British Army Lance Corporal Liam Tasker who was killed during the conflict in Afghanistan, wears her son's medals as she holds Grace, a search dog with the British army, wearing a Dickin Medal, Britain's highest award for bravery by animals that was posthumously awarded to Theo, a bomb-sniffing army dog, following a special ceremony held at Wellington Barracks, in central London, Thursday, Oct. 25, 2012. Theo, a Springer Spaniel, worked alongside Lance Cpl. Liam Tasker, searching out roadside bombs in the Taliban stronghold of Helmand Province.  Tasker was killed in a firefight with insurgents in March 2011, and Theo suffered a fatal seizure hours later. It is the highest award any animal can receive while serving in military conflict.
