How many preview birds do we get?

On the Red Field, the squad views all target except the XBird from Station 5. When they have shot Stations 1-4, they view the XBird from Station 5 before attempting the target. On the White and Blue Fields at each station, the first shooter is allowed one full flight of all targets as singles on that station menu. On the Green Field the squad views all the targets including the XBird before shooting begins on Station 3.
