The choke hold is taught during boot camp in the Marines. I don’t know if it is today or not. It can be used to only make the victim lose consciousness. The longer or tighter the hold, the more severe the results, including death. Marines are also taught counter measures to get out of a chokehold or lessen the fighter’s grasp. It was part of the martial arts program taught at that time.
In today’s society ;
Even if 2 men are engaged in a fight and 1 of the men can put a chokehold on his victim and he is only put into a state of unconsciousness, he could be charged with felonious assault and/or attempted murder, depending on who started the fight.
