Unit motto: "By strength and guile"

The Royal Navy's equivalent of the SAS, the SBS are a largely unknown yet truly deadly fighting force. They are trained to battle it out in extreme conditions, both above and beneath water.

It was the SBS who went into the Falklands three weeks before the main amphibious attack, capturing South Georgia and using it as a base of operations to send out intelligence gathering teams all across the island.
