In 2004, in its initial report to the Committee on the Rights of the Child under the 2000 Optional Protocol on the Involvement of Children in Armed Conflict, Switzerland stated:
The measures taken by Switzerland to ensure that members of the armed forces who have not attained the age of 18 do not take a direct part in hostilities are contained in articles 8 and 11 of the Federal Act concerning the Army and Military Administration (LAAM) and article 8 of the Ordinance on the Recruitment of Conscripts (OREC). Under the LAAM, article 8, paragraph 2, the requirement to enlist takes effect at the beginning of the year in which a person subject to military service reaches the age of 19 and lapses at the end of the year in which he or she turns 25. Under the OREC, article 8, paragraph 1, only those conscripts who reach the age of 19 during any given year are called up to recruitment sessions.

Switzerland’s Protection of Civilians in Armed Conflict Strategy (2009) states: “The rights and needs of children in armed conflicts are also inadequately taken into account and respected. For example, thousands of children are still being abducted, recruited or forced to participate in hostilities.”

Switzerland’s ABC of International Humanitarian Law (2009) states:
Child soldiers
It is estimated that there are around 300,000 child soldiers in the world today. Some are recruited by force while others are volunteers, in some cases for ideological reasons and in others just as a way of obtaining food. The Optional Protocol of 2000 to the [1989] UN Convention on the Rights of the Child provides for measures to ensure the reintegration in society of children who have served as combatants. The Protocol completes and strengthens the provisions of the two [1977] Additional Protocols, prohibiting compulsory recruitment and direct participation in hostilities before the age of 18. Furthermore, it calls on the States Parties to adopt measures to prevent armed groups from recruiting persons below the age of 18 and from deploying them in combat operations. The recruitment of children below the age of 15 in armed forces or other armed groups is regarded as a War crime.

In 2011, in a statement during an Interactive Dialogue with the Special Representative of the UN Secretary-General for Children and Armed Conflict at the 66th Session of the UN General Assembly, the permanent representative of Switzerland stated:
Switzerland is particularly concerned about two issues: the fact that more and more children –moreover very young and handicapped – are being used for the transport of explosives; and disrespect for the rules and standards related to detention. In this regard, Switzerland recalls that before being treated as offenders, children should be considered as victims, considering the often forced nature of their participation in hostilities.

In 2012, in its combined second, third and fourth periodic reports to the Committee on the Rights of the Child, Switzerland stated:
537. The revised version of the laws implementing the [1998] Rome Statute of the International Criminal Court, which entered into force on 1 January 2011, establishes that the offence of “recruitment or use of child soldiers” is a war crime under the Criminal Code and the Military Criminal Code. The provision punishes anyone who conscripts or enlists children under 15 into the armed forces or armed groups or makes them participate in armed conflict.
