According to some sources, Gabon had conscription in the 1980s.   
The 6 December 1960 Law-Decree nr. 4 (published in Journal Officiel de la République du Gabon, 1 January 1961) has created the national armed forces and instituted compulsory military service. 
A 1997 UN report states that there is no conscription. 
It is unclear whether conscription is enforced and what its legal basis is.
It is not known who is liable for military service and how long military service lasts for.
postponement and exemption
No information about this is available.
According to D. Bangoura, the army "gathers, in principle every year if the financial means are sufficient, youth from all over the country to serve for a fixed term". 
In the country, military conscription is the largest foundation of national integration and the easiest to organise. 
2 Conscientious objection
There is no legal provision for conscientious objection and there is no substitute service. 
3 Draft evasion and desertion
Refusing to perform military service is punishable by imprisonment. 
No further information is available.
