The Marine Corps is once again calling up Marines from the Individual Ready Reserve, according to a Stars & Stripes article.

The upcoming call-up will mark the fourth time since August 2006 that the Corps has dipped into the IRR to fill shortfalls in the active-duty force. The Corps plans to screen between 1,700 and 1,800 Marines, of which it hopes about 550 will get orders for Iraq. Of the 60,000 Marines in the IRR, about 70 percent have deployed to combat at least once, according to the article.
