Yea, after having a couple jerkwads mess with me as a smack at the zoo, I always tried to avoid personally challenging people. Instead, I'd either challenge them with the task or try to get them to challenge themselves. I always saved the personal challenges for when I had no other way to get through to someone or they were pulling a hardcore attitude. And even then I'd never fight fair, because it's really bad for discipline to challenge a troublemaker and lose. Of course, in the kinder gentler AF, "challenging" someone usually meant pushups, a run, mental exercises under physical stress, etc.
It usually worked... Looking back at it there are only a few times I wish I'd done something different when training lower class cadets.
