"Operators" generally aren't responsible for too many lives as they tend to operate in small units. Many of them are highly skilled as individuals and work well on small teams. When you start talking Company or Battalion command in regular units then you can start talking about being responsible for lots of others lives. Many Special Ops types can't fit into large units because they can't accept or handle being responsible for so many people outside their immediate circle. SF guys usually only care about themselves and their team.
