Which tactic is characterized by a surprise attack using small arms and bombs?

The characteristic of a tactic that involves a surprise attack using small arms and bombs aligns with the nature of a raid. A raid typically involves a sudden and quick assault on a target, with the aim of achieving a specific objective, such as capturing or killing targets, destroying supplies, or gathering intelligence. Raids can incorporate various offensive measures, including the use of small arms and explosives, to maximize impact and achieve their goals swiftly before retreating.

In contrast, the other options represent different forms of attack or operations. Skyjacking refers to the illegal seizure of an aircraft and does not involve a ground-based surprise attack. Bombing is focused specifically on delivering explosive ordnance over a target, usually from a distance, rather than engaging in a close-quarters confrontation. Assassination targets an individual rather than employing a broader tactic of surprise assault with simultaneous use of small arms and explosives. Therefore, the qualities of a raid best encapsulate the described tactic.
