Different than honor, the levels of which I imagine might vary quite a bit from Scout to Scout, I feel like a sense of duty runs pretty deeply through most if not all Scouts.
A feature of an organisation that moves its field operatives around a lot, has them gone for considerable periods of time, and often working in small teams for extended durations? Similar to the Navy, but less military? If there were a lot of operatives that didn't form lengthy relationships due to the difficulties derived from all of that, there'd be a pool of available people, or at least the ones that didn't settle down after they discharged.
