(1) Men who have attained the age of eighteen may be required to serve in the Armed Forces, in the Federal Border Police, or in a civil defence organisation.

(2) Any person who, on grounds of conscience, refuses to render military service involving the use of arms may be required to perform alternative service. The duration of alternative service shall not exceed that of military service. Details shall be regulated by a law, which shall not interfere with the freedom to make a decision in accordance with the dictates of conscience and which shall also provide for the possibility of alternative service not connected with units of the Armed Forces or of the Federal Border Police.

(3) Persons liable to compulsory military service who are not called upon to render service pursuant to paragraph (1) or (2) of this Article may, when a state of defence is in effect, be assigned by or pursuant to a law to employment involving civilian services for defence purposes, including the protection of the civilian population; they may be assigned to public employment only for the purpose of discharging police functions or such other sovereign functions of public administration as can be discharged only by persons employed in the public service. The employment contemplated by the first sentence of this paragraph may include services within the Armed Forces, in the provision of military supplies or with public administrative authorities; assignments to employment connected with supplying and servicing the civilian population shall be permissible only to meet their basic requirements or to guarantee their safety.

(4) If, during a state of defence, the need for civilian services in the civilian health system or in stationary military hospitals cannot be met on a voluntary basis, women between the age of eighteen and fifty-five may be called upon to render such services by or pursuant to a law. Under no circumstances may they be required to render service involving the use of arms.
