The term "fighting persons" can imply aggression and violence, which may not always be appropriate. Instead, we can use alternatives such as "combatants," "warriors," "fighters," "battlers," or "soldiers" to describe individuals engaged in conflict. Other words that convey determination and bravery without promoting violence include "resisters," "opposers," "challengers," "confronters," or "adversaries." Additionally, we can consider more specific terms depending on the context, such as "boxers," "wrestlers," or "martial artists." Using diverse and accurate synonyms can enrich our vocabulary and communication skills, while also avoiding negative connotations.
