Armbar focuses on fixing the enemy's chest and neck with both legs, then fixing the opponent's hand joints, and then crossing.

It is estimated that when you use armbar, there is no joint prevention or the span is not in place. This trick is very lethal. If used properly, even a novice can dislocate the enemy's arm.
