Sergeant Nigel Coupe, from Lancashire, has been praised as a fiercely dedicated soldier but also a man devoted to his wife and "two little princesses".
Sgt Coupe was the most senior solider on the doomed Warrior and more than 10 years older than any of the five other men who died.
He lived in Lytham Saint Anne's, with his wife Natalie, and he left two daughters, Ella and Jasmine.
His family have released a statement which said: "Nigel was a loving grandson, son, husband and daddy who doted on his two little princesses.
"He dedicated almost 17 years of his life to the Army and we are immensely proud of all that he achieved in his short life.
"He was loved by everyone and will be sorely missed."
According to the Ministry of Defence, Sgt Coupe joined The Queen's Lancashire Regiment in 1996 - a unit which subsequently became 1st Battalion The Duke of Lancaster's Regiment.
In Afghanistan he was attached to the 3rd Battalion The Yorkshire Regiment as a Warrior Sergeant in 7 Platoon, Corunna Company.
Lieutenant Colonel Nicholas Wood, Commanding Officer, 1st Battalion The Duke of Lancaster's Regiment, said: "Sergeant Nigel Coupe was quite simply an outstanding soldier who epitomised all that a sergeant from The Duke of Lancaster's Regiment should be.
"Professional, courageous and utterly dedicated to his job, he was highly regarded by all who worked with him."
