The army IS the Finnish Defence Force. I do not think it is a prototype, far from it. I think the reason why you can not find much about it is that most of us from/in Fenno Scandinavia do what you call 'bushcrafting' in a different way. If we stay in one place, then the main thing is fishing and hunting. If we trek overland, the main thing is the walking, maybe a spot of fishing, taking pictures, looking. The actual tenting, shelter and the associated duties ( cooking, tent, collecting a snack in season) are a means to do other stuff, not the actual main goal.
