The word "战术" is formed by combining two characters: "战", which means "battle" or "war", and "术", which means "art", "method", or "technique". The concept is constructed by directly linking these two ideas, where the method or art is specifically applied to the domain of combat, resulting in the integrated meaning of "the art of battle" or "tactics". It is a conceptual fusion, much like creating the compound "battle-art", where the first element defines the field and the second defines the activity within it.
