The Role of Identity in Team Sport

For forces like the royal marines to thrive they have to create an incredibly strong sense of identification so that people will perhaps make the ultimate sacrifice for the benefit of the group. In team sport doesn't there have to be a sense of individual identity alongside the team identity for an individual to flourish or am i getting that wrong? Jeremy: I think there has to be asense of role clarity so i i think that people need to understand where they fit into the hole because it's become part of who i am and  that's what the royal marines are really great at doing.
