Gabriele Zamparini has now published an essential article at The Cat's Blog, which proves that they're lying. It includes this:
If the BBC (and most of the media) trust only military sources, then a military source they’ll have. From [the] US Army's "Field Artillery Magazine" [pdf]:9. Munitions. The munitions we brought to this fight were 155-mm highexplosive (HE) M107 (short-range) and M795 (long-range) rounds, illumination and white phosphorous (WP, M110 and M825), with point-detonating (PD), delay, time and variable-time (VT) fuzes. (…) White Phosphorous. WP proved to be an effective and versatile munition. We used it for screening missions at two breeches and, later in the fight, as a potent psychological weapon against the insurgents in trench lines and spider holes when we could not get effects on them with HE. We fired “shake and bake” missions at the insurgents, using WP to flush them out and HE to take them out. (…) We used improved WP for screening missions when HC smoke would have been more effective and saved our WP for lethal missions. (…)
THE FIGHT FOR FALLUJAH - TF 2-2 IN FSE AAR: Indirect Fires in the Battle of Fallujah By Captain James T. Cobb, First Lieutenant Christopher A. LaCour and Sergeant First Class William H. Hight”
And this, from an April 2004 article in the North County Times:
Fighting from a distance
After pounding parts of the city for days, many Marines say the recent combat escalated into more than they had planned for, but not more than they could handle.
"It's a war," said Cpl. Nicholas Bogert, 22, of Morris, N.Y.
Bogert is a mortar team leader who directed his men to fire round after round of high explosives and white phosphorus charges into the city Friday and Saturday, never knowing what the targets were or what damage the resulting explosions caused.
Millikin, 21, from Reno, Nev., and Alexander, 23, from Wetumpka, Ala., quickly made the adjustments. They are good at what they do.
"Gun up!" Millikin yelled when they finished a few seconds later, grabbing a white phosphorus round from a nearby ammo can and holding it over the tube.
"Fire!" Bogert yelled, as Millikin dropped it.
The boom kicked dust around the pit as they ran through the drill again and again, sending a mixture of burning white phosphorus and high explosives they call "shake 'n' bake" into a cluster of buildings where insurgents have been spotted all week.
They say they have never seen what they've hit, nor did they talk about it as they dusted off their breakfast and continued their hilarious routine of personal insults and name-calling.
