conscription not enforced
Conscription is enshrined in art. 21 of the Argentine constitution which states: "Every Argentine citizen is obliged to bear arms in defence of his country and of this Constitution". Yet, there has been no compulsory military service since 1994. However, in the event of armed conflict or a national emergency, conscription may be re-introduced. The 5 January 1995 Law on Voluntary Military Service (Law no. 24.429 Servicio Militar Voluntario) regulates military service. According to this law, military service is performed by volunteers. But, if insufficient volunteers present themselves for enlistment in the armed forces, art. 19 of Law 24.429 allows the government to introduce compulsory military service. Such decision must be approved by the National Congress. In that case 18-year-old men may be called up for up to a year's military service under the terms set out by the previous Law 17.531 on Compulsory Military Service.   
All men and women aged 18 to 24 may volunteer for performing military service. 
2 Conscientious objection
In case the government decides to introduce conscription, all conscripts have a right to conscientious objection. Art. 20 of Law 24.429 states that individuals who, for "profound religious, philosophical, or moral reasons," are unable to perform their compulsory military service will be required to perform a substitute social service. This may be performed in such areas as public health and environmental projects, but in wartime it must consist of activities to do with civil protection and defence.  
procedure and practice
How this right is exercised in practice is not known, as from 1995 onwards conscription has not been enforced.
It is neither clear whether those serving voluntarily are entitled to be released from the armed forces should they become COs.
3 Draft evasion and desertion
Deserters are tried by military courts, but the punishment for desertion is not known. When desertion is regarded as treason, the Code of Military Justice permits the death sentence.
From 1987 on all military court verdicts have had to be reviewed by the civilian federal court of appeals. 
When the 1995 Law on Voluntary Military Service was passed, all deserters and draft evaders were amnestied. 
Up to 1995 there was compulsory military service. Young men were registered as conscripts when they were 17 and were called up to perform military service at 18. In the years before 1995 only 10 percent of conscripts actually served. Approximately 90 percent were exempted - either by lot, or because of physical disability or by paying a sum of money. 
President Menem decided to abolish compulsory military service on 13 June 1994 and the Law on Voluntary Military Service was passed in January 1995. This surprisingly swift achievement of abolition was partly due to the public backlash over the beating to death of Omar Carrasco, a young army recruit, on 6 March 1994. Although there had been many cases of conscripts suffering human rights violations, this time the family denounced the incident and received enormous public support over their demand for justice. Two conscripts, a sergeant and one lieutenant, accused to have participated in the death of Carrasco, are in jail but all claim they are not guilty. A trial is going on to judge those who tried to cover up the case, but sofar no military has been found guilty.  
Before the 1995 law was passed there was no legal provision for conscientious objection. Refusal to perform military service was punishable by up to four years' imprisonment. Several Jehovah's Witnesses have served three to four year prison sentences in the Campo the Mayo, the largest military base in Argentine. In the past COs have also been sentenced to perform a year's non-combatant service in the armed forces.
Ever since 1984, following the Falkland/Malvinas War, FOSMO (Frente Opositor al Servicio Militar Obligatorio - Front Opposing Compulsory Military Service) has campaigned both for the right to conscientious objection and for the abolition of compulsory military service.   
6 Annual statistics
The armed forces comprise 73,000 troops, which is about 0.21 percent of the population. There is a 375,000 strong reserve force. 
In the final years of conscription only some 16,000 conscripts served annually, that is 10 percent of the total number of conscripts. But when conscription was abolished, the military said they required 26,500 volunteers. In 1994 there were more than 200 COs.
