On January 31, 1966, a booby trap was detonated killing two men from Company B, 1st Bn(M), 5th Infantry. The event emotionally jolted some the men of the company and impressed upon them that this was the real thing. Not training, not practice. Soldiers get horribly wounded and disfigured in wartime. Soldiers die in wartime! These were people you knew, if only by sight. One moment they are laughing, talking, breathing, living and the next moment they are very horribly dead. How thin and delicate the thread between life and death is, was a lesson soon to be indelibly implanted in the consciousness of the soldiers of the battalion. Some wondered who would be next.
