from rural regions such as the Berner Oberland, fanning the enmity between the traditionally conservative rural population and the urban working class. The third complete mobilization of the army took place during World War II under the command of Henri Guisan (see also Switzerland during the World Wars). The Patrouille des Glaciers race, created to test the abilities of soldiers, was created during the war. In the 1960s and 1970s, the armed forces were organised according to the "Armee 61" structure. Horse mounted cavalry (specifically dragoons) were retained for combat roles until 1973, and were the last non-ceremonial horse cavalry in Europe, as were bicycle infantry battalions until 2001. Since 1989, there have been several attempts to curb military activity or even abolish the armed forces altogether. A notable referendum on the subject was held on 26 November 1989 and, although defeated, did see a significant percentage of the voters in favour of such an initiative. However, a similar referendum, called for before, but held shortly after the 11 September attacks in 2001 in the US, was defeated by over 77% of voters. In 1989, the status of the army as a national icon was shaken by a popular initiative aiming at its complete dissolution (see: Group for a Switzerland without an Army) receiving 35.6% support. This triggered a series of reforms and, in 1995, the number of troops was reduced to 400,000 ("Armee 95"). Article 58.1 of the 1999 constitution repeats that the army is "in principle" organized as a militia, implicitly allowing a small number of professional soldiers. A second initiative aimed at the army's dissolution in late 2001 received a mere 21.9% support. Nevertheless, the army was shrunk again in 2004, to 220,000 men ("Armee XXI"), including the reserves. In 2016, the Swiss Federal Assembly voted to further reduce the army from 140,000 men to 100,000 men, reducing the time of basic training from 21 weeks to 18, but also to increase the military budget by 2.4 billion Swiss francs. Personnel As of 1 March 2017, the Swiss Armed Forces consist of 120,496 people on active duty (in Switzerland called Angehöriger der Armee, shortly AdA, engl.: Member of the Armed Forces), of which 9,163 are professionals, with the rest being conscripts or volunteers. Women, for whom military service is voluntary, numbered 929: less than 1% of the total, with over 25% thereof being officers. The numbers had
