One Defense official said the effort wasn't designed primarily to reduce the size of any potential troop increases, but to ensure that everyone being deployed was in a "mission critical" job.

"If he is asking for more, he certainly wants to ensure we are maximizing the use of everyone that is here now," said the official, who spoke on condition of anonymity.

Most of the dozens of combat outposts and outlying bases in Afghanistan have soldiers or Marines assigned to gates or guard towers. But the Pentagon official said those troops could be shifted to more valuable duty.

"They just stare out from the tower. So let's bring in contractors," the Pentagon official said. "Now you can have a thousand more troops in the field."

Any needed job left vacant could be filled by hiring Afghans or using military contractors, officials said.

But contractors serving in some capacities, notably as security guards in Iraq, have been accused of excessive violence and wrongdoing.

In Afghanistan, a government watchdog group said Tuesday that many of the 450 private guards employed by a subsidiary of U.S.-based Wackenhut Services Inc. have engaged in lewd and drunken behavior in a "Lord of the Flies" environment. The workers guard the U.S. Embassy in Kabul, the capital, under a $189-million contract.

State Department officials said they are investigating.

Critics have charged that the military has relied too heavily on contractors in Iraq and Afghanistan, handing over too many crucial responsibilities to outsiders.

A recent Congressional Research Service found that there were more contractors than military personnel serving in Afghanistan. The report was based on figures gathered in March, before additional troops ordered by Obama began arriving.
