One of Han Cha Kyo's students told me he asked him about non contact sparring and his response was in the military that they could not risk injury from contact sparring because because they might need to go into combat and fight for real at any moment.
NAM, Tae-hi (남태희; 南太熙; 19 March 1929 – 7 November 2013) was a pioneering South Korean master of taekwondo, and is known as the 'Father of Vietnamese Taekwondo.' With
Hong Hi Choi, he co-founded the
Oh Do Kwan and led the twelve
original masters of taekwondo of the
Korean Taekwon-Do Association (KTA).
While fighting in the Korean War, Nam gained famed for hand-to-hand combat during the Battle on Yongmun Mountain:
"In the dark, Nam heard a noise, ran into somebody, and tried to grab the man's hair during the scuffle. The Chinese soldier was trying to do the same. With no light, the only way to distinguish friend from foe was by grabbing at a head, because communists had crew cuts and South Koreans had slightly longer hair. In that trench, Nam felt short hair — almost bald — and he struck. His enemy fell."He heard another soldier. He punched, flailed. Ran on. As the two armies fought in the dark trenches, Nam tapped men's heads when he could. Crew cut meant attack; long hair, pull back. He could not use a bayonet and fought with his hands all night, thinking of nothing — no mind — stumbling through the dark, striking , kneeing, moving. When he fell, he would stand again. The next day, the communists retreated from the trenches and the fighting continued with guns... The next day's battle ended as night fell, but Nam kept fighting. Most of his thirty-one men were dead, and he had not slept for three nights. He had not eaten in how many days? He worked out that he had missed nine meals. He collapsed from exhaustion..."That day, during the retreat, Nam wandered to a spot where he had fought during the night before. He found many dead bodies and counted more than two dozen with no bullet or knife wounds. They were the ones he had hit during the night, the ones with broken faces and bones, but there was no time to dwell on these things. Seeing the Chinese divisions weakened , all the South Koreans, including the main line ten kilometres away, counter-attacked and chased the communists over Yongmun Mountain. Thanks to Nam and his battalion, one Korean division backed by an American division defeated three communist divisions. The battle would soon be in Korea's military records: a famous, horrific lesson in how to defend a mountain top against a 360-degree attack.
