In Belgium we've had a conscript army for most of it's existence. A few decades ago it was abandoned. The conscripts were very poorly paid and on average not very well motivated. We had conscript soldiers, NCO's and officers, depending on their certificates. They had to serve approx 1 year (in Germany a few months less than in Belgium). They were not very well liked by the volunteers.
Positive for the concript army is that it is cheap (depending on their pay of course, but this is almost always very low). Also the conscripts learn discipline and after doing their time they are more mature.
Drawbacks are a less motivated force. When they finally start to know their job they go back to civilian life.
I prefer a volunteers army. Small, efficient and well equiped. In Belgium it is only small
