This is not to say that you should never punch or kick or disregard the value of learning proper striking techniques. Even Jigoro Kano realized the importance of atemi waza and kept the techniques alive in judo katas. However, one should also recognize the limitations and risks of striking techniques in combat and on the street. Consider the United States Army Field Manual on hand to hand combat which states: “Strikes are an inefficient method of ending a fight. However, they are a significant part of most fights, and a solider must have an understanding of fighting at striking range. It is important to note that while at striking range, you are open to being struck. For this reason, it is often better to avoid striking range.”
