Update: I have the book. It's better than I expected and the clip
There are some good clips brought up after the above clip finishes - Kimura demonstrating...
This clip - the guy's holding a rifle and bayonet and just sitting there - anyone in his right mind would be trying to break the shime any way he could - stabbing behind himself with the bayonet, reaching back for the eyes, and so on - one assumes that if there's someone choking you when you're escorting him at bayonet point, he's going to render you either unconscious or dead, so - yeah, right... sit there...
Must look up this book.
