It is at this point I should point out that the team doesn't necessarily need to elect a single leader. They could have the role divided among several team members, for example they could have their tactician who plans missions and gives them their orders, a field leader who is able to adjust for complications during battle and rally the team back together and a public face who to the outside world is the team's leader and deals with the politics of it all. 

Either way, updated:
