The recruitment standard rejects theatrical toughness in favour of someone quiet, responsible, and willing to let a completed mission be the only reward. Courtney's notice contrasts two men in a £15 folding boat with a £350,000 submarine and 52 trained crewmen, while stressing that the submarine's price captured only part of its value to the war effort. One careless act could expose the submarine and every life aboard. Raiders therefore had to understand naval rank, etiquette, secrecy, and the authority of the submarine's captain rather than behave as independent adventurers. They were also expected to check equipment personally, plan for contingencies, and protect scarce folding boats before leaving the parent submarine.
