i'm jäger. I served in Jäger Artillery Regiment, Self-Propelled Howitzer Battery 1994-1995. When the last real Jäger died from the original group, Väinö Valve, i was in the army.
What kind of song you are looking for? I have seen the movie "Winter War", are you looking for song "Vilppulan urhojen muistolle - Finnish White Army Song"?
These fellows, just inspired Hitler for the BARBAROSSA! Campaign. Why? The FINNS! simply defeated the RUSSIANS! as the song say, you simply the BEST! 🙌🧐
