The guillotine choke is a chokehol in martial arts applied from in front of the opponent. The choke involves using the arms to encircle the opponent's neck in a fashion similar to a guillotine. The technique is either a type of tracheal compression restraint that prevents air flow to the lungs, or a blood choke depending on how it is applied. When executed from the ground, the person applying it will try to control the opponent by the hips, for instance using a closed guard. This is done to prevent the opponent from escaping the hold, and to be able to apply additional pressure by extending the hips.
