Hello, Greg!
First, thank you for serving our country. You're in a most critical region of the world serving the interest of democracy over tyranny and subjugation. Let's just say that no news is good news.

- The kumite provide a common ‘language’ so that individuals from different dojo can train together (presuming of course that they are allowed to do so by their sensei)
- Essential defensive skills such as timing, distancing, body movement and reception techniques can be isolated, practiced and observed by the sensei with corrections as needed
- The sensei can control (to a degree) the variables in the exercise to push the student “enough” but not to the point that he or she is completely overwhelmed and either loses confidence in the defensive technique (typically due to incorrect execution) and/or suffers frequent injuries
- The kumite by their nature are intrinsically predictable and students often begin to develop sloppy habits, e.g. retreating before an attack has been initiated, lackadaisical attacks, etc. This can be addressed by adding variation to the drills.
That is one of the best descriptions of these tools and how they are used, Greg. Nicely stated.

My personal belief is that the yakusoku kumite are tools – no more and no less. The utility of any tool depends both upon the quality of the tool itself and the skill of the craftsman – in this case the sensei and how he or she utilizes it in the dojo.
I am less concerned, honestly with what the original intent in creating these drills were, as long as I can use them for my particular purposes in training my students. Personally, I have very little interest in training students to be successful in the tournament arena so my intent is to use these drills as a training aid/stepping stone for self-defense purposes, remaining very conscious of their limitations.
Bravo!
In medicine, we call this (initially) an
off-label use of the therapy. In some cases such as minoxidil for hair loss, the off-label use (now as Rogaine) ends up being the primary reason why the drug sells well on the market. Minoxidil initially was designed to treat hypertension. Dermatologists and cardiologists rarely speak to each other in patient management, but this pharmaceutical tool designed for the heart people turned out to be a bigger money maker for the beautiful people. And nobody in medicine is arguing.
And FWIW, the same is true for Sildenafil. Its initial use was for treating poor circulation in the heart muscle. We used it in several experiments back in my days in cardiology research. But the big money maker (under the market name Viagra) was in... treating poor circulation in the heart muscle.

Any guys out there complaining?
The frustrating part of discussion of these drills for those who use them in training is these kinds of arguments.
- These drills were designed to teach people how to spar. Therefore...
- People perform these drills by backing up. Backing up is the wrong thing to do in a fight. Therefore...
To start with, I couldn't imagine being a martial arts teacher
without having my students engage in sport sparring. Sparring isn't necessarily the desired end, but it's a means to an end. Anything that helps people get up to speed on THAT tool (sparring) and reduces the chance that they will get injured and lose valuable training time is good for me.
And as for the backing up thing... I don't teach that way. I teach people about working with the line of force. As such, strictly backing up is done either as simulating a classic flinch (your amygdala WILL make you back away from certain lethal threats) or to "bait" the person into a finishing technique. Otherwise the operative word is staying off of that line of force, and using that mantra as a means to staying on the offensive.
Are the drills primitive? Yes. Do they simulate real fighting? Certainly no more so than Sanchin. Is it useful? To the degree that a teacher can simplify a partner exercise to a few elements (while holding others constant), then it's a means to working on those elements when a teacher sees that there are learning opportunities.
Thanks for the inspiration, Greg!
