Check out the SBS, Special Boat Service, kit. SBS are always prepared for every contingency. Sgt Casey in Naomi Kryske's crime/suspense novel, The Witness demonstrated this. Few Yanks know as much about the SBS as does Naomi. Some of what she incorporated in her character were based on previously highly classified information about elite special forces. Sgt Casey will return in the sequel, The Mission, to be published in summer, 2015.
