Who is better marine or sailor?

The comparison between a marine and a sailor depends on the context and the specific roles each fulfills. Marines are typically trained for amphibious combat and land operations, combining naval and ground warfare skills, while sailors primarily focus on operating and maintaining naval ships and equipment. Each has its own strengths and capabilities, making them essential to naval operations but serving different purposes. Ultimately, "better" is subjective and depends on the specific mission or situation at hand.
