exploits of The Lwów Eaglets (Polish: Orlęta Lwowskie) young fighters who died defending the city of Lwow in Galicia, Poland from invading Ukrainian & Russian forces during the Polish-Ukrainian War (1918–1919). The name "Eagle Owls" is also appropriate because 307 Squadron's role was night-fighter defence. 308 Squadron's badge uses an old Polish design previously used for 121 Escadrille. It uses the same emblem but facing the opposite way (right instead of left) and it is now enclosed in a diamond shape. 315 Squadron's badge uses an old Polish design previously used for 112 Escadrille in the Brygada Poscigowa (Pursuit Brigade) tasked with the defence of Warsaw. The only difference is that it was rotated 30 degrees clockwise so the triangle is pointing down instead of left, with the bird more vertical and "315" was added. 316 Squadron's badge uses an old Polish design previously used for 113 Escadrille in the Brygada Poscigowa (Pursuit Brigade) tasked with the defence of Warsaw. The only difference is that it was rotated 30 degrees clockwise so the triangle is pointing down instead of left, with the owl more vertical and "316 SQ" was added. 317 Squadron's badge uses an old Polish design previously used for 151 and 152 Escadrilles in the pre-war Polish "Narew Army Group". The blue version of that badge for 151 Esc. is closest to the 317 Sqn. badge. 318 Squadron's badge uses the coat of arms of the City of Gdansk – a red shield with two white crosses and a golden crown above. The only additions are the golden wings surrounding the shield and the number "318" at the top. 663 Squadron's badge uses the Polish red and white chequered square "roundel" set as a diamond with a Polish eagle flying and carrying an artillery shell. It has the letters "DSA" beside the number "663". Note : In the Polish Air Force, their Air Force unit badges had two versions depending on which side of the aircraft they were painted, so that the emblem was always pointing or facing forwards. So on the port (left) side, the emblem faced left (forward) and on the starboard (right) side, the emblem faced right (forward). For the RAF Polish squadrons, there was only one design with most facing left, but 308, 316 and 663 squadrons' emblems faced right.
