From this page:
Combatively, jukendo, with it's limited target areas and insistence on only using thrusts with the bayonet, would render it in part ineffectual. To this end the Japanese military supplements its training with jukenkakuto, which is similar to the kind of training that most military forces do. with many variations of technique, live blade training and a host of other exercises and drills. However, even in this training, the use of many of the standard jukendo techniques is prevalent. In fact, in talking with many of the high ranking teachers, it is evident that they view jukendo - as opposed to using the bayonet in a realcombative function - as having very little to with any technical differences: instead they indicate that the main difference is one of motivation or
psychologicalintent. In jukendo, one is trying to score a point, in real bayonet fighting one is trying to down one's opponent.
