Fallon resigned Tuesday amid media reports that he was at odds with the White House over Iran. Dempsey used to be his deputy.

US President George W. Bush is not expected to nominate a permanent successor to Fallon until David Petraeus, top US commander in Iraq, submits reports on Iraq to Congress on April 8-9.

It looks very likely that Dempsey could stay in the new post, but other candidates are also in Bush's mind, including Petraeus.

Born in 1952, Dempsey's military career spans over three decades.

He was the commander of the 1st armored division in the early stages of the Iraq war and was promoted to Centcom deputy commander last year.
