Getting hurt using unarmed combat techniques is part of the learning process. You can't properly apply a joint lock, bar or other dissabling technique without having it done to you and then doing it to a partner in practice. Going through the motions doesn't cut it. You need to learn what amount of force it takes to properly perform the technique, and what is needed for control of the opponent.

You need to hit and be hit, not killing blows but solid contact none the less, just to know what to expect. That's called conditioning.

Takedown and control techniques are something that the military would use in a capture situation. You don't necessarily want to kill everyone. If you're not going to capture them, a good solid jab to the throat will do nicely.

Something I tell the kids:

Hand to hand, no problem. All you'll get is bruises. It's good for you.
Hand to knife, be ready to get cut; possibly pretty bad. Runnings a good choice.
Hand to gun, hope your life insurance is paid up
