The Reserve and the Reserve Officers in Finland

The Finnish Reserve Officers’ Federation is a voluntary organisation dedicated to developing the skills and abilities of reserve officers, contributing to national defence and supporting national security. The Federation has about 28 000 members. The Federation is formed by 300 member associations organised into 20 reserve officer districts.

The Finnish Reserve Officers’ Federation and our close partner, The Finnish Reservists’ Association, are not part of the Finnish Defence Forces organisation. All the reservists’ organisations closely cooperate with our national Defence Forces. To learn more about our reserves’ responsibilities, you are welcome to visit these web site hosted by the Finnish Defence Forces:

The total reserves of the Finnish Defence Forces include 900,000 men and women. The wartime strength of the Defence Forces is 280,000. 

Thanks to the high readiness of the Defence Forces and a large reserve produced by the general conscription model, Finland has a credible and pre-emptive threshold against the potential use of force and the ability to defend all of the countries.
