A Royal Marine killed by a blast in southern Afghanistan was Marine Anthony Hotine, 21, of 40 Commando, the Ministry of Defence has said.
He died on Wednesday in an explosion in the Sangin district of Helmand province, while on foot patrol with Afghan National Army soldiers.
He was born in Torquay, Devon, and lived in Warminster, Wiltshire.
Marine Hotine's death takes the number of UK service personnel killed in Afghanistan to 290.
He had served in Sangin, in Helmand province, in 2008-09 before returning to the area in April as a signaller.
His commanding officer revealed the marine had hoped to go back again next year for his third deployment to Afghanistan.
Marine Hotine, who was known as Tino, lived with his parents and younger brothers, Callum and Kieren.
In a statement released by the MoD, Marine Hotine's family said: "We are so proud of Anthony - he lived and breathed the Royal Marines and he was a 'Bootneck' through and through.
"Words cannot describe the devastating sense of loss felt across the whole family. He was an amazing son, big brother and grandson to us all."
Lt Col Paul James, Commanding Officer 40 Commando Group, Combined Force Sangin, said Marine Hotine was a "brilliant young man who was at the height of his profession".
"Bright, selfless, dedicated and keen-spirited, he was an outstanding marine. Having previously served in Sangin a little over a year ago, he wanted to return next year for his third deployment - he was one of the most loyally committed men I have ever met," he said.
"An ambitious character who always had a plan, he strove for greatness, both in his life and in his work, and invariably achieved it. He had an infectious wit, a sharp mind and a big and generous heart."
Defence Secretary Liam Fox said: "Marine Anthony Hotine's experience and professionalism made him a highly respected member of 40 Commando.
"His loss will come as a huge blow to his friends and colleagues within the Corps, and nothing will soften the pain felt by his family at this difficult time.
"But Marine Hotine's important role in this crucial mission for Britain's national security, for which he made the ultimate sacrifice, will not be forgotten."
