The Finnish Defence Forces (Finnish: Puolustusvoimat, Swedish: Försvarsmakten) are responsible for the defence of Finland. A universal male conscription is in place, under which all men above 18 years of age serve for 165, 255 or 347 days. Alternative non-military service and volunteer service by women are possible.
Finland is the only non-NATO EU country bordering Russia. Finland's official policy states that a wartime military strength of 280,000 personnel constitutes a sufficient deterrent. The army consists of a highly mobile field army backed up by local defence units. The army defends the national territory and its military strategy employs the use of the heavily forested terrain and numerous lakes to wear down an aggressor, instead of attempting to hold the attacking army on the frontier.
Finland's defence budget equals approximately 2.9 billion euros or 1.2% of GDP. The voluntary overseas service is highly popular and troops serve around the world in UN, NATO and EU missions. Homeland defence willingness against a superior enemy is at 76%, one of the highest rates in Europe.
After Finland's declaration of independence on 6 December 1917, the Civic Guards were proclaimed the troops of the government on 25 January 1918 and C.G.E Mannerheim was appointed as Commander-in-Chief of these forces the next day. Fighting between the White Guards (as the Civic Guards were commonly known) and the Red Guards had already broken out about a week before around Viipuri, in what became known as the Finnish Civil War.
In the war, the Whites were victorious in large part thanks to the leadership of Mannerheim and the lead by example offensive mindedness of 1,800 German-trained Finnish Jägers, who brought with them German tactical doctrine and military culture. The post-war years were characterized by the Volunteer Campaigns that came to an end in 1920 with the signing of the Treaty of Tartu, which ended the state of war between Finland and Soviet Russia and defined the internationally recognized borders of Finland.
