It is used together in a dummy set to start anti-tank guided missiles called the “Imitator lotu” (flight simulator?) PPK POK-35 (35 MIS B). This device has 4 26mm launchers, from which the NI-ppk special charges are triggered by means of an electric pulse (device based on the air signal launcher EKSR-46).
Such a flying tracer imitated the start and flight of a guided anti-tank projectile (ppk). This was used to reduce the costs of training soldiers, so that they could familiarize themselves with the characteristics of phenomena that accompany the launch of ppk, instead of firing a real ppk.
