The limited answer on Royal Navy close-quarters training

Did the Royal Navy train its sailors for close-quarters combat during World War II?

To an extent, yes, but the panel gives no further detail about the training.

The answer is a qualified yes: Royal Navy sailors received close-quarters training to some extent during the Second World War. The panel does not specify weapons, a syllabus, the units involved, or how broadly the instruction was delivered. The exchange therefore establishes some training without supporting a fuller claim about standardized doctrine or intensity. Whether the instruction centered on boarding drills, small arms, or combat ashore remains unspecified.
