POI conducted by the Airborne School, Special Forces Regiment (Airborne). Poland The Polish Odznaka Spadochronowa was based on the previous award called the Odznaka Pilota Wojskowego, or Military Pilot Badge. It was first introduced by notable Polish sculptor Władysław Gruberski in 1919 and was accepted shortly afterwards as the sign of all the pilots of the Polish Air Forces. The badge featured an eagle with wide spread wings, holding a laurel wreath in his bill. In 1941, after the creation of the UK-trained 1st Independent Parachute Brigade, a similar symbol was adopted as the sign of all Polish paras. It featured a diving silver eagle. The symbol was also adopted by the cichociemni and nowadays is used by all branches of the Polish Army. Also, the Polish special unit GROM adopted a modified version of the symbol as its emblem. It is commonly (though informally) referred to as gapa (diving Eagle). Singapore The Silver Wings is awarded upon successful completion of the Basic Airborne Course conducted by the Parachute Training Wing, School of Commandos. First awarded to the pioneering batch of 27 NSFs from 2nd Company, 1st Commando Battalion (1 CDO BN) of the Commandos formation, it comprises a pair of outspread wings on both wigs of a deployed parachute, with the word "SINGAPURA" below the canopy. With the design sanctioned by 1 CDO BN's Commanding Officer, Tan Kim Peng Clarence, it is differentiated by a crimson velvet backing for Commandos, while those of the Commando Parachute Jump Instructors have a golden velvet backing. Non-Commandos wear the badge without any backing.
