The word 突击 is formed by combining two characters: 突, which carries the meaning of "sudden" or "to break through", and 击, which means "to strike" or "to hit". Conceptually, they merge to create a vivid, action-oriented compound where the sense of a sudden, forceful breakthrough (突) is immediately followed and executed by a decisive, attacking strike (击). The formation is akin to a rapid, two-stage mental image, first the surprising eruption, then the focused blow, which together encapsulate the idea of a swift and concentrated assault on a task or target.
