There are many kinds of military service systems, which can be basically divided into two types: one is compulsory military service system, also known as conscription system. This system is that the state forces citizens to perform military service for a certain period of time within a certain age range through laws. The other is voluntary military service system, also known as conscription system. Under this system, citizens voluntarily enlist for military service and sign service contracts with the army. Soldiers who perform compulsory military service are called conscripts.
