I'm a little toward Andy's interpretation on this particular one. A large part of any lack of success would be simply the times in which those folks were doing their thing, as Andy mentioned, though I do think the Jingwu might have gone on to become outstanding soldiers in the actual army if any of them pursued that route. If maintaining relevancy for as long as possible into the 20th century were the goal, that particular combination of skills would have been more suited for the Swiss citizen guard training, certain African locales, and the remaining bush farmers of the Australian outback.
Unfortunately, for a modern citizen wanting modern-relevant skills in firearms, he's still best served by training in fully modern home defense, combat handgunnery, professional urban assault, special teams operations, or Marine Corps infantry training, depending on exactly what skill sets he wants. Nothing else from the dusty halls of Asian martial arts even has a remote analog to such skills.
Also as Andy mentioned, shooting is but one slice of a large pie in general military training. However, for the individual citizen, most of the bulk of modern military training for the general soldier, which includes a great variety of comprehensive training for an equally great variety of MOS's, is so specialized for large-unit, large-intensity conflict that it is, tactically, utterly irrelevant to the needs of the individual citizen. For the individual citizen, that renders shooting skills a much larger percentage of the training pie than for the soldier. It's still not the only thing, by any stretch, and there's still room for even the good-old empty-hand skill sets.
The needs of the individual citizen seeking maximal training in protecting his family or property are not identical nor fully interchangeable with the needs of the individual battlefield soldier. Frankly, the citizen has to do a lot more himself, since he's not working within nested units, has no backup necessarily, has no recon intel on the enemy, has no long-range detection capability, does not enjoy the luxury of overwatch support, and cannot call for fire support or armed exfiltration from the site of conflict. He's truly the "army of one" for his situation. Luckily, thanks to the Castle Doctrine, he's also not limited by asinine rules of engagement.
