Amazing! What's going on: The beam of light is an infrared target illuminator (IR spotlight). The guys on the ground point it at the spot they want the aircraft to shoot. It is invisible to the naked eye.

Air support is provided by a UH-60 Blackhawk helicopter gunship. The rapid shots are 20mm cannon, the slower shots are 30mm cannon and there are a couple of 2.75" rockets thrown in. The green twinkling lights near the target were probably muzzle flashes from enemy weapons.

The blinking lights closest to the camera are IR "good guy" lights to let the air support identify friendly forces.
