The point man, while obviously surprised, emptied a whole magazine 20 round magazine from his M14, straight into the left eye of the Giant Chameleon, and coupled with the support fires from the rest of the squad, the Giant released him and ran back into the forest. The squad withdrew a full click and requested napalm air support over the whole grid square where they had just been.
Not being quite sure what the target was, the US Navy still sent in four Skyraiders and dropped napalm on the target area. The next day a careful search by the squad, by then reinforced by the rest of the platoon, was unable to find anything definitive.
