Leader

The Leader is the head honcho of any given goup. Leaders are in charge of what the next course of action for the team is.

Jobs
The Leader has a few important jobs. Most of the affairs are dealt with by the Second in command.

Guidence
The Leader's main job is to help other members of the group with problems they're dealing with. Giving advice, stopping disputes, that sort of thing.

Planning
A Leader will give assignments to the rest of the team in order to succeed in a mission.

Carrying on the battle
If the rest of the team is at their limit in a fight, the Leader is usually the one remaining to insure the enemy's defeat.
