During a training excerise @ the US Army training center @ Wildflecken ,germany;at appx. 23:30 hours, at an elevation appx.8k ft. alt. I was in a foxhole over looking abattlion of tanks firing at simulated enemy targets below the ridge. I happen to look over my shoulder and upward at a clear semi starry night sky, when I observed 3 circular shaped objects that glowed a semi-bright orange. At first, I thougth that they were the the back exhaustes of 3 F104 starfigther jets that were going to participate in engaging the tanks simulated targets also. But what happened next , sort of scared me a little into the realization that I migth be observing a UFO phenmomena, because all of a sudden the circular shapes were turning into cyclinderical in shape. I tried to measure there size by extending my arm in front of my face at a 45 deg angle toward the obj. & mea. bet. my left forefinger & thumb and mea. it to be 3" for each obj. They continued to glow the same color and almost stopped in mid flight for appx bet. 30 - 45 sec . and then cont. to move slowly ,then zoomed out of existence. During the observation I called my buddy who was at the exterm end of our formation (I was 25 yards next to him & the next man was 25 yards to the right of me etc.)to see what I saw and acknownledge I was not crazy. He made the same observation.
