The Iraq War is getting a new name, according to ABC News.

Previously known as Operation Iraqi Freedom, the mission will now be called Operation New Dawn.

In a memo to Adm. Mike Mullen, chairman of the Joint Chiefs of Staff, Defense Secretary Robert Gates says the new name is meant to correspond with the withdrawal of American troops from the country. It will take effect in September 2010.

The new label is "a strong signal that Operation IRAQI FREEDOM has ended and our forces are operating under a new mission," Gates wrote.

This isn't the first time "New Dawn" has been used by the U.S. military in Iraq, however. As ABC notes, "Operation New Dawn was the name for the bloody and grueling 2004 battle for Fallujah."
