The short answer is "yes". But there is a longer answer as well. North County Times (San Diego) staff writer Darrin Mortenson, along with photojournalist Hayne Palmour, was embedded with a Marine unit involved in the aborted April, 2004 assault on Fallujah. His account of their use of "Willie Pete" is excellent, and discusses how white phosphorous was used when they were there.
