Groundfighting strikes

Important points:

1. It's important to be in a dominant position to strike.
2. Covering up is suicide on the ground. You have to be aggressive and get up, or reverse, neutralize, then clear. It nearly impossible to cover up from the ground when immobilized. You need to take away the base of the striker to prevent his strikes from having power, reverse to a stronger position, and only cover up when necessary.
3. You DON'T want to be on the bottom position in a real fight!
4. You want to avoid taking someone to the ground in a real fight, unless it's your best opportunity to end the fight, as in 1) you have superior numbers, 2) you know the defender isn't armed, and 3) you know you can neutralize the opponent quickly.
