Cpl Harrison had been in the Marines for seven years
The widow of a Royal Marine killed in an explosion in Afghanistan on Sunday has paid tribute to "the most fantastic husband I could ever have wished for".
Rebecca Harrison, from Taunton, told the Ministry of Defence website the death of her husband, Cpl Christopher Harrison, had left her "broken".
The 26-year-old, serving in Bravo Company, 40 Commando, was killed while on foot patrol in Sangin in Helmand.
His death takes the toll of UK service personnel killed in Afghanistan to 285.
In a statement, Rebecca Harrison said: "Even though I knew and fully supported what Chris did as a Royal Marine and the dangers he was facing, I am still broken by his loss.
"Chris was my life, he was my motivator and my inspiration, my rock, the one person with whom I shared everything.
"It hurts me beyond words knowing that I will never have my beloved husband by my side ever again and we will never raise the family that we so desperately craved to complete our lives together."
His parents, Martin and Gill Harrison, also paid tribute, saying: "He was an outstanding young man with qualities way beyond his young years.
"Although he had to be tough, demanding and in peak physical condition to do his job as a Royal Marine, he was also caring, kind and considerate to those he truly loved.
Lt Col Paul James, his commanding officer, said Watford-born Cpl Harrison, who had been with the marines since 2003, "embodied the best of his generation".
He described him as "fit, bright, dedicated and incredibly courageous".
He added: "A larger than life character, both in stature and personality, he was one of the few men who was known across the whole of 40 Commando.
"He achieved legendary status amongst his cohort having overcome snakebites in Brunei and delivering rapid and accurate mortar fire support on this, his second deployment to Afghanistan."
