L/Cpl Paul Farrelly, 27, from Runcorn in Cheshire, and Lt Tom Mildinhall, 26, from the Queen's Dragoon Guards (Welsh Cavalry), died on patrol in Basra.
The parents of Lt Mildinhall, from Battersea, south London, have paid tribute to their "beautiful, talented and loving son".
Two British TV journalists were killed by a car bomb in Baghdad on Monday.
Soundman James Brolan, 42, and camera operator Paul Douglas, 48, died while filming in Baghdad for US news network CBS. A colleague was left critically ill.
Lt Mildinhall's parents added: "Our world is in pieces and our country has again lost one of its best."
The two soldiers were killed in an attack in Gizayza, north-west Basra, when they were on routine patrol in an armoured Land Rover, in support of operations to disrupt the insurgency.
Lt Mildinhall was described by his commanding officer, Lieutenant Colonel Anthony Pittman, as "a thoroughly capable officer".
"He led by example and his soldiers responded positively, safe in the knowledge he had their best interests at heart," he said.
"It was typical of his command style to insist he physically led the more dangerous patrols, as he was doing last night when his troop came under attack and he suffered a fatal injury."
The MoD said he would "be missed by those who served alongside him "for his extremely dry sense of humour and razor sharp wit".
After completing his officer training at Sandhurst in April 2004 his first deployment in Iraq was helping train Iraqi border police.
He undertook this difficult task with "considerable enthusiasm and diligence", quickly making a "considerable impact", said the MoD.
His second deployment to Iraq began a month ago.
Lt Mildinhall, who studied at Durham University, was also a keen downhill ski instructor.
L/Cpl Farrelly, known as "Fas", grew up in Runcorn, but moved to Rhyl, north Wales, when he was around 16.
The married father-of-three was a "committed family man" who spoke "often and fondly" of his wife Natalie and their three children, said the MoD.
His commanding officer Lt Col Pittman said he stood out as a "natural leader".
"He embodied much of what is best about soldiers in the British Army; selfless, determined, humorous and steadfast in the face of adversity," he said.
L/Cpl Farrelly joined the Army in March 2002 and was judged top recruit during his basic training in Winchester. He was on his third deployment in Iraq, which began a month ago.
Welsh Secretary Peter Hain paid tribute to the two men.
"The deaths of these two young soldiers serving in the Welsh Cavalry is a tragedy and a reminder to us all of the courage and dedication of our troops engaged in Iraq in very difficult circumstances," he said.
"I extend my deepest sympathy to their families, friends and colleagues."
The two soldiers bring the toll of British forces personnel to be killed in the Iraq war to 113. Nine have been killed this month, including five who died in a helicopter crash.
Defence Secretary Des Browne told the BBC the upsurge in violence in Iraq was a cause of "major concern".
He called on Iraqis to "get a grip" on security and on those behind the violence through local and central governance.
"We have promised to and we will continue to remain in Iraq until the Iraqi government is confident that the Iraqi security forces are capable of providing security without assistance from the coalition forces," he said.
