THE BURNED OVER DISTRICT

The US is reverting to its bad habit of hiring mercenaries to fill out the necessaries. Whether they are hired gunsels or hash slingers for the mess hall, they keep the number of actual soldiers down despite costing more than traditional means of the military taking care of its own needs.

The U.S. government is preparing to boost the number of private contractors in Iraq as part of President Barack Obama's growing effort to beat back Islamic State militants threatening the Baghdad government, a senior U.S. official said.

How many contractors will deploy to Iraq - beyond the roughly 1,800 now working there for the U.S. State Department - will depend in part, the official said, on how widely dispersed U.S. troops advising Iraqi security forces are, and how far they are from U.S. diplomatic facilities.

Still, the preparations to increase the number of contractors - who can be responsible for everything from security to vehicle repair and food service - underscores Obama's growing commitment in Iraq. When U.S. troops and diplomats venture into war zones, contractors tend to follow, doing jobs once handled by the military itself.

"It is certain that there will have to be some number of contractors brought in for additional support," said the senior U.S. official, speaking on condition of anonymity...

There are now about 1,750 U.S. troops in Iraq, and U.S. Defense Secretary Chuck Hagel last week ordered deployment of an additional 1,300.

The U.S. military’s reliance on civilians was on display during Hagel's trip to Baghdad this month, when he and his delegation were flown over the Iraqi capital in helicopters operated by State Department contractors.

The problem, the senior U.S. official said, is that as U.S. troops continue flowing into Iraq, the State Department's contractor ranks will no longer be able to support the needs of both diplomats and troops.

After declining since late 2011, State Department contractor numbers in Iraq have risen slightly, by less than 5 percent, since June, a State Department spokesman said.

This all seems very familiar.
