Attacks on U.S. Troops in Iraq Grow in Lethality, Complexity - washingtonpost.com
"As U.S. troops push more deeply into Baghdad and its volatile outskirts, Iraqi insurgents are using increasingly sophisticated and lethal means of attack, including bigger roadside bombs that are resulting in greater numbers of American fatalities relative to the number of wounded.
Insurgents are deploying huge, deeply buried munitions set up to protect their territory and mounting complex ambushes that demonstrate their ability to respond rapidly to U.S. tactics. A new counterinsurgency strategy has resulted in decreased civilian deaths in Baghdad but has placed thousands of additional American troops at greater risk in small outposts in the capital and other parts of the country."
More lovely unintended consequences of this brilliant "war" - we're training them to be better killers.
