I think we saw here TWO different documents.
I believe that Adrian's document was given after the service ended. It says in the beginning "Uvolnitelnyy bilet", which is given when person is dismissed.
Larry's document is different. It is like a certificate that a person completed his service and now he is in "opolchenie" - militia and will be going to service in time of war, etc.
All these documents have a lot of information for genealogists.
All the best,
