Royal Marine (British Special Forces). Known to each other as "Royal" but the rest of the British Forces know them as bootnecks. This nickname is derived from them cutting the top from a leather boot and wearing it like a modern neckbrace to stop sailors cutting their throat while they guarded officers on board British sailing ships in the days of old.

More from Urban Dictionary
British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
