A more throughout explanation: Mutual combat refers to a situation where two or more individuals engage in a physical altercation with each other willingly and consensually, without one party being considered the aggressor or victim. In legal terms, mutual combat typically implies that both parties have agreed to fight each other and have therefore consented to the physical confrontation.
Example: In some jurisdictions, mutual combat is a defense that can be used in cases where both parties willingly engaged in a physical altercation.
