Al-Qaida in Iraq takes heavy losses.
And remember, the UPI article is describing only a pair of on-going operations. The enemy has been sustaining these types of losses since the surge hit high gear. And, if anything, the number of enemy casualties reported in the press is understated.
Obviously, AOI losses aren't the only barometer of battlefield success. But they are indicative of several, positive trends. First, we're taking the fight to the enemy and holding areas that were previously terrorist strongholds. Secondly, our tactical success has bolstered the confidence of Iraqi civilians, who (in turn) are providing us more/better intelligence on where the enemy is. That, in turn, allows us to plan an execute more effective operations, which results in more dead terrorists.
