Chicago ? Seeking experience in wartime, President-elect Barack Obama intends to re-enlist Defense Secretary Robert Gates as head of the Pentagon — if only temporarily — and has chosen a retired Marine general to be White House national security adviser, officials said Tuesday.

Gates and retired Gen. James Jones would bring decades of experience to the administration of a 47-year-old commander in chief who campaigned on a pledge to redeploy combat troops in Iraq within 16 months while simultaneously ramping up the U.S. military presence in Afghanistan.

While Gates has accepted Obama’s appointment, it was not clear that Jones had done the same.

Obama also has also offered the post of secretary of state to Sen. Hillary Rodham Clinton of New York, his rival in the campaign for the White House. Officials have not yet disclosed whether she has decided to give up her seat in Congress to join the Cabinet.
