In literature, the term combatant is versatile, evoking both the literal figure of a warrior engaged in battle and the metaphorical fighter grappling with internal or ideological conflicts. It is employed to depict soldiers or strategic figures whose prowess is celebrated on the battlefield, as in discussions of tactical mastery inspired by Sunzi’s writings [1, 2, 3]. At other times, the word characterizes participants in duels or tournaments, emphasizing both the physical valor of the combatant [4, 5, 6] and the societal admiration they can inspire [7, 8]. Moreover, its use often contrasts active fighters with those outside direct conflict, highlighting the ethical dimensions of war [9, 10] and even extending into personal battles, as seen when an individual internalizes the role of a combatant in life’s ongoing struggles [11].
