Remember that this talk of "aikido techniques" is really quite arbitrary. It would be more accurate to speak of them as "martial techniques." The techniques themselves are based on study of the human body and its physiology. What each style brings to bear is a different philosophy on the application of these principles
My thoughts exactly.
The wrists/limbs whatever, only move so many ways. I've seen kote gaeshi in many other forms of martial art, how and when you apply them makes all the difference.
Does the army teach ukemi?
Btw, Merry Christmas everyone
