Refresher training is a form of updating military knowledge of the reservist troops. After one has completed the conscription service, he or she can be called for refresher training for some amount of days.
In the Finnish Defence Forces (FDF) Officers and NCOs can be ordered to refresher training for 100 days in addition to their original military service and the rank and file (privates and other lower ranks) for 75 or 40 days.[1] The amount of refresher training that a reservist is called to depends on the importance of the reservists assignment, deployment, the amount of special training (i.e. training that requires constant upkeep of skills) and willingness. The aim is to train the most important wartime units at intervals of about 5 years. The average duration of the exercises is approximately 5 days and nights. Many never get called to refresher training, some get called frequently and some even apply for voluntary additional training. The obligation for refresher training ends at the age of 60 for Officers and NCOs and at 50 for the lower ranks.
