What is a sneak attack as defined in the context of ship security?

A sneak attack, in the context of ship security, refers specifically to attacks conducted by swimmers or small boats. This type of attack is characterized by its attempt to approach undetected and exploit vulnerable points in a ship's security. Swimmers or small boats can maneuver close to a target without drawing attention, enabling them to launch surprise assaults or sabotage operations.

This method leverages stealth and can pose significant risks to naval vessels, especially when they are moored or stationary, as they may have limited defenses against such close-range threats. Recognizing sneak attacks highlights the importance of vigilant watchstanding, effective surveillance measures, and preparedness for unconventional threat vectors.

The other options describe different types of attacks that generally involve larger forces or different platforms, such as aerial assaults or submarine attacks, which, while dangerous, do not align with the specific definition of a sneak attack in the context of ship security.
