Conscription is enshrined in sect. II art. 9(b) of the Constitution, which states: "Every able-bodied Dominican citizen shall perform such civilian and military service as may be required by the country to ensure its defence and preservation." 
It is not clear if conscription is actually enforced.
The government stated in 1989 that it does not consider military service to be among the duties of its citizens. 
Several other sources also state that there is no conscription.
