Im in "The Swedish Anti-Aircraft Voluntary Training Association", it's for youths in the ages of 15 to 20, i've been there since 2007. What we do is like preparing for what used to be military service, but now a days the swedish armed forces changed, so now it's a job to be a soldier, not some kind of duty. Today is the thing i'm a part of more like another way for the swedish armed forces to recruit new young soldiers by making them a part of it at the age of 15 without being soldiers. I'll probably apply for some basic training this summer, and then i'll see what happens after it.
Pretty hard to explain, hope you get it
