From the Washington Post:
President Obama announced in March that he would be sending 21,000 additional troops to Afghanistan. But in an unannounced move, the White House has also authorized — and the Pentagon is deploying — at least 13,000 troops beyond that number, according to defense officials.
…The deployment of the support troops to Afghanistan brings the total increase approved by Obama to 34,000. The buildup has raised the number of U.S. troops deployed to the war zones of Iraq and Afghanistan above the peak during the Iraq “surge” that President George W. Bush ordered, officials said.
Oh, also: Guantanamo Bay is still open.
