it just sucks. If you're a regular trooper you'll get away with only six months of training, but if you want to gain some ranks, you'll have to stay for a whole year in the bloody place. The first two months are sheer hell as you'll have to march all around the base with tons of stuff in your backpack. After that you'll start learning the stuff you are supposed to do during the war. Would be nice if it worked, but the whole service is full of constant squabbling and you just generally sit in a wet forest holding your bladder and try not to piss your pants while guarding some meaningless junk.
The RK-62 is a piece of crap compared to the weapons used by Finns during WW2 and you're just glad when your military service is over. Unless you happen to be a lunatic like me and write a diary about those horrible experiences alongside with a few photos.
