A Royal Marine who was killed in a bomb blast in Afghanistan has been named by the Ministry of Defence.
Nigel Dean Mead, 19, from 42 Commando Royal Marines, was involved in an operation to search a compound in the Loy Mandeh Wadi area of the Nad-e Ali (North) district of Helmand province.
His mother, Amanda Jones, said: "I could never write enough words that would truly say how much I loved and thought of you. You're not a one in a million son, you are one in a hundred million."
Paying tribute to her son, Miss Jones added: "You had the most wonderful and warming personality, one that I have never seen in anyone else, nor will ever see again.
"You gave me strength when I most needed it and you were the rock that supported me through my life.
"Although you turned out to be a proud and heroic Royal Marine, you will always be my little blue-eyed boy."
She said she had been left with a "broken heart for the rest of my life" because she will never again hear her son's "cheeky laugh", or hear him say, "I love you mam".
The marine, known as Deano to his friends and colleagues, lived with his mother and sister Jessica in Carmarthen.
He joined the Royal Marines as his first job in October 2008 at the age of 17, and he was the youngest marine to pass out from his troop.
On Sunday morning his company, Lima Company, were conducting a cordon and search operation of compounds with the Afghan National Security Forces. Marine Mead was fatally injured by an IED (improvised explosive device) blast shortly after his helicopter landed and his company began to move towards the compounds.
