Getting and maintaining a leadership position amongst small groups of men.

I am looking for a book to read on both getting and maintaining the leadership position amongst small groups of men (5-12 or so, roughly the number found in sports teams.

It should deal with issues such as:

1. Dealing with enemies.
2. Creating trust and alliances, even love for you as a leader.
3. Having a "right-hand man".
4. Dealing with the problem of passive aggressive / reverse dominance tactics.
5. Dealing with dominant behaviour in other men.

I've read 48 Laws of Power but that's gears towards being a power player amongst many other power players, often with bigger fish in the system–like a courtier in a Medieval European court. I've read books by military generals–too large a scale.

I'm looking for something that can teach me how to be a power player in small groups - like in our ancestral social environment (tribal social structures).
