This is a 10-minute video of an AC-130 Spooky gun ship flying a support mission against Al-Qaeda in Iraq. What you see is the infrared viewing screen of a 20mm cannon fire Gattling gun. Because of their accents the ground troops they are supporting appear to be British or Australian. They came under fire during an ambush from a huge number of Al-Qaeda militants in a small town in very crowded quarters. The AC-130 gunship is standing off a considerable distance and is presumably unseen by the enemy as they are picked off one by one and two by two. The enemy must be carrying with them grenade launchers, grenades or other explosives because very often when they are hit by the 20mm canon fire there is an explosion. Each time a vehicle is hit the cannon fire causes the gasoline tank to explode. U.S. military spotters on the ground and on the aircraft help direct the AC-130 Gattling gun fire at the enemy combatants. Each time the gunner taps the gun trigger it looks like about six rounds are fired and he doesn't stop firing for the entire 10 minutes. Towards the end of the video you see two U.S. helicopters move into the LZ to evacuate the friendly forces. At different times you can hear the friendlies shout out.... "danger close" ...which means the 20mm canon fire is within a few meters of their own positions on the ground.
