11.3 Making them work
Revelation brought a new gang system... which requires some understanding.
To be a squadron commander you need leadership V. After which, each level of Wing Commander (prereq: Leadership 5) allows for an extra squadron under your command. Finally, each level of Fleet Command (prereq: WC 5) allows for an extra wing under your command.
To boost the people in your squadron, wing or fleet you must be either a commander or be set as the booster. If you're the fleet commander you will boost the whole fleet. If you are a Wing Commander, you will boost everyone in your wing, etc. The fleet commander can set you as the squadron, wing or fleet booster you're in regardless of your leadership skills (as shown in the tree up there).
