Security Option 11 was initiated by WSC and Base CSC. BAF #1&2, were formed. At 11:40 p.m., the following information was learned:
Upon arrival, 9:32 p.m., at Site #L-9. LSAT. Jenkins & Raeke, dismounted the SAT vehicle to make a check of the site fence line. At this time Raeke observed a bright light shinning vertically upwards form the rear of the fence line of L-9. ( There is a small hill approximately 150' behind L-9 )
Jenkins stayed with the SAT vehicle and Raeke proceeded to the source of the light to investigate. As Raeke approached the crest of the hill, he observed an individual dressed in a glowing green metallic uniform and wearing a helmet with visor. Raeke immediately challenged the individual, however, the individual refused to stop and kept walking towards the rear fence line of L-9. Raeke aimed his M-16 rifle at the intruder and ordered it to stop.
The intruder turned towards Raeke and aimed a object at Raeke which emitted a bright flash of intense light. The flash of light struck Raeke's M-16 rifle, disintegrating the weapon and causing second and third degree burns to Raeke's hands. Raeke immediately took cover and concealment and radioed the situation to Jenkins, who in turn radioed a 10-13 distress to Line Control. Jenkins responded to Raeke's position and carried Raeke back to the SAT vehicle. Jenkins then returned to the rear fence line to stand guard.
Jenkins observed two intruders dressed in the same uniforms, walk through the rear fence line of L-9. Jenkins challenged the individuals but they refused to stop. Jenkins aimed and fired two rounds from his M-16 rifle. One bullet struck one intruder in the back and one bullet struck one intruder in the helmet. Both intruders fell to the ground, however, approximately 15 seconds later Jenkins took cover and the light missed Jenkins.
The two intruders returned to the east side of the hill and disappeared. Jenkins followed the two and observed them go inside a saucer shaped object approximately 20' in diameter and 20' thick. The object emitted a glowing greenish light. Once the intruders were inside, the object climbed vertically upwards and disappeared over the Eastern horizon.
