The British Special Boat Service (SBS) is a special forces unit of the United Kingdom's Royal Navy. It specializes in maritime operations, including reconnaissance, counter-terrorism, and direct action missions. The SBS is known for its rigorous selection process and extensive training, which prepares its members for various challenging environments. Established in 1940, the SBS has a close relationship with the Special Air Service (SAS), another elite unit in the British military. Both units often collaborate on operations and share similar tactics. The SBS is particularly skilled in underwater and amphibious warfare, making it a vital asset for naval operations.
