This is quite funny btw, how people seem to think that it's either education or national service...
In Finland, it ccertainly isn't so. One year, max, for national service. You get free food, free clothing, roof on top of your head, training and skills and you get paid a little on top. Since you have until almost your 30 to complete the service, you can do the service before uni, in the middle of the uni (if you get bored of books etc) or after the uni. It does nothing to hinder education.
Just take a look at our 'stats'.

The Finnish Defence Forces consists of a cadre of professional soldiers (mainly officers and technical personnel), currently serving conscripts and a large reserve. The standard readiness strength is 34,700 people in uniform, of which 25% are professional soldiers. A universal male conscription is in place, under which all male Finnish nationals above 18 years of age serve for 6 to 12 months of armed service or 12 months of civilian (non-armed) service. Alternative non-military service and volunteer service by women (chosen by around 500 annually)[59] are possible. Finland is the only non-NATO EU country bordering Russia. Finland's official policy states that the 350,000 reservists, armed mostly with ground weaponry are a sufficient deterrent. Finland has one of the largest armies in Europe per capita.
The Finnish Defense Forces favor partnerships with Western institutions such as NATO, WEU and the EU, but are careful to avoid politics.[60] Finland's defence budget equals about ?2 billion or about 1.4?1.6 % of the GDP. In international comparisons Finnish defense expenditure is around the third highest in the EU.[61] Voluntary overseas service is popular and troops serve around the world in UN, NATO and EU peace-keeping missions. Residents claim around 80 % homeland defense willingness, one of the highest rates in Europe

In tertiary education, two, mostly separate and non-interoperating sectors are found: the profession-oriented polytechnics and the research-oriented universities. Finns used to take student loans and scholarships, but for the past decades the financial risk has been moved solely to the government. There are 20 universities and 30 polytechnics in the country. The World Economic Forum ranks Finland's tertiary education #1 in the world.[82] Around 33% of residents have a tertiary degree, similar to Nordics and more than in most other OECD countries.
More than 30 % of tertiary graduates are in science-related fields. Finnish researchers are leading contributors to such fields as forest improvement, new materials, the environment, neural networks, low-temperature physics, brain research, biotechnology, genetic technology and communications.[85]
Finland is highly productive in scientific research. In 2005, Finland had the fourth most scientific publications per capita of the OECD countries
