I have searched around a few times and can't find it. What is the average size and make up of an Imperial tie squadron. Also Rebels, are they just whatever pilots we can throw together or do they have an actual organization for X-wing, Y-wings and so on.

A TIE squadron is 12 ships, organized into 3 flights of 4, which are made of elements of 2 ships (leader and wingman).
