...most complicated techniques are just combinations of simple ones...
As I have noted before in various threads, I like the "skill developing drills" and even reference striking patterns like the clock, Presas 12/13, etc because an entire class of varrying skill levels can be doing the same thing at their own skill level.... the beginners doing the basic version, the intermediate folks doing the passing version, the advanced folks dealing with additional layers of attack/defense, etc. All the students stay happy and somewhat challenged and when they are ready, it is very easy for them to conceptually move to the next level.
Most of us will never be 100%, but just because we can't have a jab like Ali doesn't mean we shouldn't practice the technique for example... and practice will eventually pay off. It took me six months to get the hang of the "sankyo" joint crank, but now it is one of my favorites and when training, I use it with considerable success.
To use this thread to segue into a related topic...
Part of the intent of MCMAP was to create something that couldn't be learned in "Eight Easy Lessons" or whatever. General Jones, LtCol. Bristol, MGSgt. Urso, et al wanted a system that Marines would train in over their entire career. Hence the restrictions for enlisted men on MCMAP level and paygrade... (example, must be at least a Cpl. to attend the instructor course, must be at least a Sgt. to attend the Instructor-Trainer course). A talented Martial Artist could probably learn everything in a week or two, but the average Joe or Jane off the street is going to have to put in a minimum of 247-odd hours (if I recollect correctly) to learn everything. The lower level techniques are basic, and the upper level techniques are well, less basic, but taken together with their combat conditioning work, the difficulty is nothing to scoff at for the brown, black, or "dan" (note, they don't refer to it as this) levels. I have also noticed that the naysayers who say MCMAP sucks, generally don't even have even a tan belt in the system. MCMAP will "push the learner's envelope", not to the skill level or varried array of techniques say, of the Congress Material, but there is something in it for every Marine.
