I'm figuring that the Iraqis are only get one shot at setting these trench fires. Could it be that are boys are already at the outskirts of Baghdad and they Iraqis set them so slow them up?
I'm speculating, but based upon this story.
Four US soldiers killed in central Iraq - Sky TV
LONDON, March 22 (Reuters) - Four U.S. soldiers were killed on Saturday in central Iraq, according to a reporter from Britain's Sky TV who was travelling with them.
Journalist Colin Brazier said the four reconnaissance scouts were ambushed while driving Humvee jeeps at the head of the column.
"Rocket-propelled grenades were fired, one at each Humvee, (they) killed both sets of occupants," he said in a brief live report on TV.
