Hello, is it possible to create a wing , with a 4 init wingleader and 5 or 6 inti wingmen and how do you handle the special abilities of each?

You can indeed put non-generics as 'wingmen' instead of 'wing leaders' - one option, for example, for Fenn Rau and Old Teroch - both of whom are brutal at close quarters - in a wing 'led' by a Zealous Recruit, who allows them to move at I1, making it nigh impossible to block them.

Special abilities work as normal - movement and damage-redistribution aside, the wingmen are still standalone ships and are shot at and shoot seperately.
