1.(a) Must Article 1(a)(i) and Article 2(3) of Regulation No 1408/71 be interpreted as meaning that a professional soldier on active service in Belgium, to whom the medical care provisions of the compulsory sickness and invalidity insurance applicable to employed persons have been extended, ranks among the persons covered by the regulation?
(b) If so, does the Court consider that it may be inferred from the fact that a specific branch of social security, namely medical care under the sickness and invalidity insurance, is governed solely as regards its administration by legislation of a Member State to which Regulation No 1408/71 applies, that persons referred to in Article 2(3) of Regulation No 1408/71 are or have been in fact subject to the legislation of a Member State to which that regulation applies, as provided for in Article 2(3) aforesaid?
(c) Should the reply to questions (a) and (b) be in the affirmative, must the word 'where' in Article 2(3) of Regulation No 1408/71 be interpreted as meaning that the regulation is applicable to the persons referred to therein only as regards the legislation of a Member State to which that regulation applies?
2. Must Article 13(2)(d) and Article 14c of Regulation No 1408/71 be interpreted as meaning that the employment as a civil servant of a person falling within the scope of the regulation is to be treated as activities as a person 'employed' for the purposes of the application of Article 14c.
3. Must Title II of Regulation No 1408/71, including Article 14c thereof, be interpreted as meaning that the fact that a person who ranks among the persons covered by the regulation in respect of his activities as a person 'employed', on account of which he is insured only for a single risk (in this case medical care under the sickness and invalidity insurance) is obliged with regard to his activities as a self-employed person to pay insurance premiums only in respect of the same risk, although the applicable national legislation provides for compulsory and indivisible insurance for several risks.
