Given the tactical organization of the Regia Aeronautica during World War II, this book covers the story of all the different Gruppi that were part of the 53 Stormo during World War II. The Regia Aeronautica organized their units in the basis of a Squadriglia, (Squadron) with strength of 9 to 12 airplanes. Two or three Squadriglie would form a Gruppo (Group) and two or three Gruppi would form a Storm (Wing). Often there would be autonomous Gruppi and sometimes even Squadriglie assigned to different front or sector.
The Gruppi described in this book are the 150 Gruppo “Gigi Tre Osei”, 151 Gruppo “Asso di Spade”and 153 Gruppo “Asso di Bastoni”. Also 157 Gruppo was attached to 53 Stormo briefly and therefore included in the book.
