Coalition aircraft [had] regularly been the target of hostile fire from the Deh Rawod area … Gunfire from various caliber weapons was observed throughout the day and at night, including mortars and AAA [anti-aircraft artillery] fire … Several compounds in the Deh Rawod area were positively identified as sources of this AAA fire. AAA fire had emanated from these compounds on repeated occasions over the previous two days and the source of the fires did not change. In all cases, the locations of these compounds were such that they could range and threaten coalition ground and airborne forces … As coalition ground and airborne forces approached the area, fire erupted from some of the compounds. By firing, these AAA batteries established that they were manned, armed, and operational. Their proximity to the objectives, landing zones, and blocking positions made them a threat to inbound coalition forces. Consequently, these sites were valid targets and AC-130 aircraft were directed toward them.Significant efforts were expended to ensure only the compounds that were the sources of fire were targeted. At the first targeted compound, the apparent location of most of the deaths and injuries, AAA fire was directed at the AC-130 as it approached. At one location, however, the AC-130 arrived at a target and found it to be "cold" and elected not to strike it.The AC-130 was not able to observe the AAA weapon itself. Rather, the ground location of the source of the fire was identified and fires were directed to that area. Just as the weapon itself is not seen, it is also not possible to determine if the fires from the AC-130 have damaged or destroyed the weapon. Consequently, personnel at the
