Warrant Officer Class 2 Colin Beckett, Company Sergeant Major of 3rd Battalion The Parachute Regiment, died attempting to secure an area in Shaheed, when he was caught in the roadside bomb.
Company Sergeant Major Beckett, known as Tom, was described by his colleagues as an inspirational and iconic leader.
The 36-year-old joined the army more than 20 years ago and had a "tremendous amount of operational experience'', a MOD spokesman said.
His wife Rachel, who is expecting their first child later this month - a girl already named Freya, said: "Anyone who ever met or knew Colin 'Tom' would have been touched by him in a big way and he will never be forgotten."
"He was a fantastic soldier, a great son, a good brother and friend and a truly special husband."
"My bestest friend, my soul mate, my absolute world. We love him and shall miss him so very much."
"May his love for life, strength, humour and strong character, live on forever in his baby girl Freya.''
