A British soldier killed in Basra, southern Iraq, has been named as Lance Corporal Timothy "Daz" Flowers.
L/Cpl Timothy Flowers was serving with the Irish Guards
L/Cpl Flowers, 25, who served with the Royal Electrical Mechanical Engineers, died on Saturday after an attack on the Army's Basra Palace base.
The Ministry of Defence said the soldier, who lived in Northern Ireland, was working on a vehicle when a rocket or mortar hit the site.
His commanding officer said his death had dealt "a body blow" to the company.
Major Fabian Roberts MVO, commander of the Irish Guards Company to which L/Cpl Flowers was attached, said: "He was ostensibly a quiet, modest man, who got on with his job with unstinting pragmatism and determination.
"Yet there was a depth to him intellectually and in his wider personality that made him full of surprises."
L/Cpl Flowers' death brings the total number of British service personnel killed in Iraq to 163, with 127 of those killed in combat.
He was on attachment to the 2nd Royal Tank Regiment from the Royal Electrical and Mechanical Engineers.
Defence Secretary Des Browne said: "He was doing an important job with great skill and enthusiasm in challenging circumstances.
"I know he will be sorely missed by all who knew him."
There are currently 5,500 UK troops serving in Iraq
L/Cpl Flowers had already resigned from the Army by the time he arrived in Iraq.
His commander, Artificer Quarter Master Sergeant Lee, said: "It is testimony to the loyalty and courage of the man that he extended his service to see the job through, with his friends, regardless of his own personal situation."
He described L/Cpl Flowers as a "natural mechanic".
"He was at his happiest on the Tank Park, spanner in hand," he said.
"No job was too difficult or too much trouble. The diligent endeavour that he constantly displayed was as infectious as his cracking sense of humour."
L/Cpl Flowers' death came on the same day that three RAF servicemen killed in a mortar attack on their Iraqi base on Thursday were named.
They were Matthew Caulwell, Christopher Dunsmore and Peter McFerran, who were all Senior Aircraftsmen.
