Lieutenant General Gregory S. Newbold is a retired United States Marine Corps 3-star general who served as Director of Operations (J-3) for the Joint Chiefs of Staff from October 2000 until he retired in October 2002. Openly critical of Donald Rumsfeld's plans for the invasion of Iraq, he retired partly as a protest.
