Usage
What does combatant mean? A combatant is one of the sides engaged in combat—active fighting. In war, enemy combatants are the opposing sides in the war or battle. In boxing and other martial arts, the two fighters can be called combatants. The word combat is sometimes used more broadly or figuratively to refer to active conflict between two people or groups, as in The two corporations are preparing to do combat in the courtroom. The sides in this kind of combat can also be called combatants. Less commonly, combatant can be used as an adjective meaning engaged in fighting. It can also mean inclined to fight, but the word combative is more commonly used in this way. Example: If diplomacy fails, the two nations could become enemy combatants.

Explanation
Someone who fights, especially in a war, is a combatant. Sometimes entire countries are described as combatants during military conflicts. Other names for a combatant are "fighter," "attacker," or "soldier." News stories are more likely to use this word to describe an adversary or enemy: "Enemy combatants ignored the cease fire." When they're talking about their own country's fighters, they might say "troops" or "soldiers." Combatant comes from the Old French combatant, "skilled at fighting" or "warlike."
