Which amphibious mission type is described as a Swift incursion?

• A. Assault (landing force)
• B. Demonstration
• C. Raid (Swift incursion)
• D. Withdrawal

Answer: (C)

The key idea is a rapid, surprise action with a small, defined objective followed by a quick withdrawal. That combination—speed, surprise, and a limited footprint—defines an amphibious raid, so a swift incursion is a raid in practice. The aim is to strike quickly and disrupt or destroy a specific target without staying long enough to seize and hold terrain.

This fits because an assault involves landing forces with the intent to seize and hold ground, which requires a longer, more sustained operation. A demonstration is a show of force meant to influence or deter without engaging or occupying. Withdrawal describes leaving after actions, not executing the initial, fast strike that characterizes a raid.
