There was an excellent post last night about how troops are getting great air support. I'll try to dig it up today for you.

Such airstrikes would actually be tactical in nature, not strategic. And there is certainly some close air support (missions aiding ground troops) going on, especially by the Marines. But this resistance is being done by scattered pockets, often by cowards wearing civilian clothes. So such airstrikes would undoubtedly kill innocent civilians, perhaps making our problems worse. But I can guarantee you if our troops are in trouble and the enemy location is identified, they can call in an air strike. I saw the Marines do it the night before last. Rather than advance by foot on heavy gunfire coming from a house, the Marines sat back and let an aircraft take out the house.
