to perform a commando roll, you dive forward landing on one shoulder (this depends on which hand you would use normally eg. right handed you would use your right shoulder). you land on the back part of your shoulder, and roll across your back diagonally (eg. right shoulder to left hip) when you have done that, assuming you are right handed, your left leg should be bent with your weight on that knee, and your right leg should not be bent. a word of advice, make sure your head doesnt touch the ground when you dive forward.
