Hm. What do you mean by serve your conscription? You didn't serve the time you were supposed to?
Sendou pretty much explained it for me. I served 362 days in the Karelian Brigade (just a short while ago the government shortened the service from 362, 270 or 180 days to 347, 255 or 165 days. ). 165 is regular rank and file, 255 mostly military police and medics and 362 days for drivers, specialists, NCOs and reserve officers. For example my gunner and driver served with me for the whole 362 days. Well, except for the first 8 weeks which was basic training/boot camp. This was our ride for the following ~10 months (random pic from the net):
God I loved that thing.
