So before I get to the repercussions of getting into a jiu jitsu match with a guard on duty, I wanted to clarify something.
Assault vs Battery:
The difference lies in whether or not someone was actually physically touched or if there was just a threatening intention to do so. Assault in general is when someone intends violence towards another but doesn't actually touch them. It becomes Battery only when someone is physically harmed. Things get even worse if there are weapons involved in which case it would become "aggravated assault" and "aggravated battery."
So, when it comes to these crimes committed against guards the laws are stricter than some may think. For instance, battery against a guard was reclassified from "a misdemeanor of the first degree to a felony of the third degree."
Naturally the consequences are elevated if it becomes aggravated. Check out the details here. You can also learn about the legal lingo around assault & battery here.
