Ghana has no military conscription, although according to art. 27, para. 6 of the constitution all citizens may be called to participate in the national defence.  
The Ghanian armed forces consist of volunteers and there is no conscription law to meet the personnel requirements of the forces in peacetime. 
Yet Ghana has another form of conscription. According to the 1980 National Service Act (Act 426), there is a compulsory national service which includes eight weeks of military training.
